Among the reptiles common to t11is count•·y arc the two spccicsofiunoccnt snalws already dcscrihe•l, ami tl•c J•aUlc· snake, which ]ast is of Hac same species as that of the lUis~ souri, and though abundant her(', is the only poisonous snake we have seen between the l~al'ific and the l\'lissom·i. flcsi1lc these there are the common black liz~wd and luwucd lizm·d. Of ft·ogs there arc sevet·all"inds, such as the small gs·ccn tree ft·og, the smalJ frog common in the United States, which ings in the s1wing of the year, a SJ>ccics of ft•o;; fa•cqncnting the '''ater, much Jargf'L' than the hull-ft·og, and in slJaJlC between the delicate length or the hull-fl'og·. and the shot·tm· and Jess gt·accful form of the toacl likt.•; tlw last. of wlsich, however, its body is eovcPetl with little pustul<·s. or lumps. ,l·e hal'C ncvct' heat·d it make a noise of a.uy kind.

Captain T,e,·. is killed a suaiHl ncar fhc camp tln·cf' feet and clcvru inches in l{'nglh, and 1nu •h the colour of tlae raUl<•sml.kc. 'rhc1·c was no Jloison-ous tooth to he found. It had two huudretl and (•ig-fttcen scuta on the abdomen, and 1ifly-ninc squama OJ' ha.Jt'-form('d scuta on the tail. The eye was of a modcl'ate 5izc: the ir·is of a dad( yellowish bt·own, and the pupil black. Thcl'c wa!-1 nothing remarl\able in the form of Hte heacJ, which was not so wide across the jaws as that of the poisonous <'lass of sual~cs usua.Hy are. 'rhe1·e is a species of lizard," hich we have called the horned lizard, about the size and much rescmb)iuoo in Jioom·e the o1·dinary black lizant. 'rhc belly is, not wit itstanl~ng, bl'oader, the tail shorter, aml the action much slowc•· tlwn the o1·dinary liz~u·d. It crawls like the toad, is of a. brown colour, and interspersed with Jellowish brown SJ>ots· itiscovm·- c.•l Wl.~ h minute shells, interspersed with little ho'r ny projeo~ tJOus hkc pl'ickles on the UJ>pcr Jlat•t of the body. 'rJw belly an<l throat resemble the frogs, and a1·e of a. light yellowish ~TJ the .,Ulssourf'. u1·own. The (•dge ol' the hclly is t•egulnl'ly beset with tbeso bo1·ny pt·ojcctions, which giv(~ to those cdg1's a set·t·ate ligul'c; the eye j~ small a111l of a dm·k eolou1'. Above and behind the eyes arc several 1wojretions of the bone, which being arsucd at the cxtt·<~mit ies wil h a liL·m black substance, having the app<·at·ance o(' ho1·ns srwouting f1·om the head, has iuduct•d us to call it Ulc horned li:t<u·(l. These animals arc fouml iu gn·at ahumlalWC in tltc ·andy {)~U'tS ot' the })lains, :tnd af'ler a. showcr of J'ain arc seen hasking in the sun. I~'or the greatest part of the time they arc conccalcu in holes. Tltcy are found in gt·eat number~ on the banks of the ~lis ~ som·i, and jn the plains through which we ha.vo Jlasse<l ahove the 'Vollawollahs. ~lost of the insect!;; eommon to the United States arc seen in this eouut1·y: ~:nu· h as the lmttea·Hy, the common housefly, the blowiugfly, the hor se11y, except one species of it, the gold-coloured earily, the JJhwc of which hi supplied by a :fly of <l. lu·own colour, wltich attaches itself to the same pal't of the horse, and is equally tt·oublt~somc. There arc likewise nearly all the val'ictic · of bcatles known in the Atlantic states, except the lat·gc cow beatle, and the black bcaUe, commonly called the tumhlebug. N cithrr the hornet, 1he wa 1,, nor the yellowjaci.~et inhabit this Jlart of the coun try, but there is an in!;ect resembling the last or these, though much hu·get·, which is very numct·ous, pat·ticularly .in the ltocky mountains- and on the watm·g of the Columbia; the hotly and abdomen m·e yellow, with tt·ansverse cir~ lcs of blacl'-, the head black, aud the wing.,. \Vhich fire four iu uumbet·, ol' a dark brown coJour: their nests are lmiH in the gt•omul, and reseutble that of the hot·net, with an outct• covering to the comb. These insects arc Jicrec, and sting vcl'y SC\'crcly. so that we found tbem very troublesome in i'rir;htening our horses as we llasscd the mountains.
