Show 1892.] LAND-SHELLS F R O M COLOMBIA. 297 variety of B. succinoides (Petit). The only specimen I have seen belongs to the National Collection at South Kensington. BULIMULUS KOPPELI, n. sp. (Plate XXIII. figs. 9-12.) Testa imperforata, ovato-conica, tenuis, nitens, carneo-albida luteo-straminea, plerumque maculis parvis nigro-fuscis pro-miscue conspersis picta, ad apicem carnea ; spira acute conica anfractus 6, convexiusculi, longitudinaliter Icevissime irregulariter striati; sutura leviter impressa; anfractus ultimus subventricosus, | longitudinis fere cequans, basi rotundatus; apertura subovalis, leviter obliqua, latiuseula, intus maculis anfractus ultimi transmeantibus; peristoma tenue, roseo marginatum ; marginibus callo tenuissimo junctis. Long. 25, diam. mag. 15 millim. Hab. Bogota. A pretty little shell, varying considerably in form and colour, but the lip appears to be always thin and prettily edged with red. Of the two specimens lent me for description by Mr. Da Costa, one is nearly white, profusely sprinkled with small brown spots, while the other is of a yellowish straw-colour (more decided yellow towards the apex), with only a few pale spots. I have as yet only seen very few specimens, but these exhibit considerable variations in their proportions. One apparently abnormally inflated specimen measures nearly 15 millimetres in width and only about 20 in ength; while the narrowest specimen measures scarcely more than 11 millimetres in width to 21 in height. BULIMULUS DA-COST^E, n. sp. (Plate XXIII. figs. 15, 16.) Testa anguste sed profunde umbilieata, elongata, nitida, irregulariter striata, pallide fulvo-carnea, longitudinaliter undulatim strigata, maculis parvis nigro-fuscis bifasciatim picta; spira convexo-conica, apice acuto; sutura leviter impressa ; anfractus 6, convexiusculi, ultimus spiram subcequans, basi attenuatus; columella obliqua, reflexa ; apertura subver-ticalis, intus rosea, maculis perlucentibus; peristoma simplex, leviter reflexum. Long. 26, diam. may. 11 millim. Hab. Bogota (Mus. Da Costa). I have as yet only seen a single specimen of this species, which may be found to vary as much as the last. It seems, however, to be distinct from any hitherto known. BULIMULUS GLANDINIFORMIS, n. sp. (Plate XXIII. figs. 13, 14.) Testa anguste perforata, oblonga, tenuissima, nitida, pellucida, stramineo-albida, longitudinaliter ruguloso-striata ; spira furrita, apice obtuso ; anfractus 7, convexiusculi, sutura canaliculata sejuncti; anfractus idtimus |, longitudinis cequans, basi leviter attenuatus ; apertura subovalis, fere columella rectiuscula, reflexa, perforationem tegente ; peristoma simplex, acutum. |
