characterized bv a complete prostomium and strictly paired setae 

 the likeness is increased. The length of the largest specimen is 

 82 mm., diameter 4 mm. ; 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 

 in segments xiv. and xy. 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. 



Xone of the septa are greatly thickened, nor are any of thein 

 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. Thepenial 

 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 spermathecas 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 in size of the 

 spermiducal glands.

(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. hovi-i. 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 mm. ; number of segments 145. 



The prostomium seems to be not continued across the buccal 

 lobe, but I am not certain as to this point. 



The setae are paired ; the ventral more strictly than the lateral. 



The clitelkun 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. Xone of 

 the septa are very much thickened ; those of Lx./xiii. are most so. 



The segments occupied by the sperm-sacs are somewhat unusual. 

 The sacs, which are racemose in character, occupy segments Lx., xi., 

 xii. As there were no sacs in segment x., I am inclined to believe 

 that the testes and funnels lie there, but have not seen them. 

 The spermiducal glands are slender and moderately coiled. The
