MICHAELSEN to be ornamented after the fashion so characteristic of the family 

 Geoscolicidae ; the copulatory setae also are ornamented by ridges, which is not the 

 case with the same setae in K. madagascariensis. It is no doubt possible that, as 

 he himself suggests, the ornamentation may have been overlooked, and may really 

 also exist in K. madagascariensis; but in any case the marked ridges upon the 

 copulatory setae of K. longus are wanting in the other species. The ordinary setae 

 of both the species are very markedly lateral in position, a condition at least rare 

 among earthworms.

 K kelleri, MICHAELSEN, Arch. f. Nat., 1892, p. 254. 



Definition. Length, 850 mm. Setae commence on XVIII. Male pores on XVII. Three 

 pairs of copulatory setae and glands on XIV, XV, XVI. Spermathecae three pairs in 

 XV-XVII. Hab. Madagascar. 



This species is nearest to K. longus; unfortunately the inferior state of preser- 

 vation of the specimens examined by MICHAELSEN did not permit of an at all 

 exhaustive account. The setae are ornamented. The shape of the muscular bulb at 

 the male pore is more oval in form than that of K. longus. The copulatory setae 

 bear the same form as in that species. The spermathecae are larger, but less numerous. 



(4) Kynotus michaelsenii, ROSA. 



K. Michaelsenii, ROSA, Boll. Mus. Zool. Torino, vol. vii, no. 119. 



Definition. Length, 130 mm.; number of segments, 200. Setae commence upon third 

 segment. Clitellum, XIX-XXV. Male pores on XV ; two pairs of copulatory setae on 

 XIII and XIV. Spermathecae two pairs in XIV, XV. Hal. Madagascar. 

 This species is a much smaller one than either of the other two ; the single 

 specimen examined by ROSA was compared by him to a Lumbricus rubellus in 

 general appearance. The setae appear to be, as in the other species of the genus, 

 lateral in position ; they commence much earlier than in the others. The last pair 

 of hearts is in the eleventh segment ; nothing is said about the organs of circulation 

 in the former species. In K. michaelsenii there do not appear (?) to be any sperm- 

 sacs ; but segments ten and eleven are full of masses of spermatozoa.
