Show J 895.] MR. F. E. BEDDARD ON NEW EARTHWORMS. 221 The spermiducal glands are much like those of A. platyurus. Tftey are somewhat slender and confined to their segments; the posterior pair was decidedly smaller than the anterior. The penial setae are a facsimile of those of A. platyurus. The spermathecae have two symmetrically arranged short diverticula. Hab. St. 30, Putabla, Valdivia. (10) Acanthodrilus carneus, n. sp. A number of specimens of this species were collected at Quilipue. They show when in alcohol a reddish-violet colour, which, however, is due to their tissues having taken up the colouring-matter from a Myriopod placed in the same bottle. The real colour of the worm during life is, according to Michaelsen, " schmutzig fleischfarbe : Giirtel weiss." The length of one of the largest specimens was 52 m m . by 3*5 m m . in diameter. The number of segments of this specimen was about 100. The prostomium is large and completely divides the buccal segment. The setae are paired, but not very strictly; tbe ventral setae of each pair are rather closer together than are the lateral setae. The clitellum occupies segments xiii.-xvi. and is complete all round. As is so often the case, this species is provided with a certain number of genital seta papillae ; as is also frequently the case with the worms of this genus, these papillae are subject to some variation. In one specimen there was a single eye-like papilla on the boundary line of segments x./xi. In another there were two median papillae, one upon x. and the other upon xi.; in two others, and this appears to be the more typical arrangement, there were the two papillae already mentioned and in addition to them paired papillae upon ix. The dorsal pores are quite conspicuous and begin in front of the clitellum. The internal characters are not very different from those of other species. The gizzard is well developed and lies apparently in segment vi. The last heart is in the xiith segment. There appears to be only one pair of testes and of funnels in segment x. The sperm-sacs are in segments ix., xi.; those of the latter segment are very coarsely racemose. The penial setae are unusually delicate aud slender; they taper towards the free end, which is not ornamented ; perhaps on account of their slenderness they are not of the yellow colour so usual. The spermathecae in viii., ix. are oval pouches with a wavy tubular diverticulum nearly as long. Hab. St. 3, Quilipue. |
