Show 1895.1 MR. F. E. BEDDARD ON NEW EARTHWORMS. 223 characterized by a complete prostomium and strictly paired setae the likeness is increased. The length of the largest specimen is 82 mm., diameter 4 m m . ; number of segments 150. The clitellum was not developed. There are dorsal pores. The gizzard is well developed and lies in vi., vii.; the oesophagus iu segments xiv. aud xv. is extremely vascular, being a bright red colour, which entirely disappears in the narrow section of oesophagus lying in xvi. The intestine begins in xvii. The last heart is in segment xii. None of the septa are greatly thickened, nor are any of them expended backwards in the cup-like fashion so prevalent among earthworms. Septa ix./xii. are somewhat stouter. There appears to be only a single pair of testes and sperm-duct funnels in x. The sperm-sacs in ix. and xi are very large and coarsely racemose. The spermiducal glands show the same inequality of size between the anterior and posterior pairs that has been noted in other species. They are both stout, but short and only slightly coiled. The penial setae are not particularly long; they are spatulated at the free extremity, and, when seen in profile, doubly curved in the usual way. They are not, however, ornamented. The spermathecae occupy the usual segments. The single diverticulum is nearly as large as the pouch. It is chalky white (owing to the presence of spermatozoa) and has a crenate outline. The posterior pair of spermathecae are larger than the anterior pair, which is doubtless correlated with the difference iu size of the spermiducal glands. Hab. St. 47, Corral, " Wald, unter Steinen." (13) Acanthodrilus albus, n. sp. This species again is represented by a single specimen, which I at first passed over under the impression that it was A. bovei. It has the same long and slender form and absence of integumental pigment. A. bovei, however, has not been met with so far north on the eastern side of the continent as the present species, which may perhaps be looked upon as its representative there. Length 85 mm., diameter 2 m m . ; number of segments 145. The prostomium seems to be not continued across the buccal lobe, but I a m not certain as to this point. The setae are paired; the ventral more strictly than the lateral. The clitellum occupies segments xiii.-xvii.; there are dorsal pores. The gizzard is well developed, contrary to what we find in A. bovei; it occupies the vith segment. The intestine commences as usual in segment xvii. None of the septa are very much thickened ; those of ix./xiii. are most so. The segments occupied by the sperm-sacs are somewhat unusual. The sacs, which are racemose in character, occupy segments ix.,xi., xii. As there were no sacs in segment x., I a m inclined to believe that the testes and funnels lie there, but have not seen them. The spermiducal glands are slender and moderately coiled. The |
