DESCRIPTIONS OF GENERA AND SPECIES 651 



g on XIV, open in front 'of and a little above ventral setae, Clitellum, 

 XF-XXVI. Male pore, XIX/XX, provided with a gland into which opens (?) sperm- 

 duct. First septum separates segments VI/VII j this and those up to XI/XII thickened. 

 Gizzard in FI ; calciferous glands in XII ; intestine begins about XV, with well- 

 developed typhlosole. Last heart in XII. Hab.—Passofundo, Brazil. 

 The spermathecae seem to be absent; at least there is no mention of them. 



(a) Tykonus appuni (Michaelsen). 

 Anteus Appuni, Michaelsen, ibid., p. 318. 



Definition. Length, 380 Mm. ; breadth, 10 mm. ; number of segments, 136. Setae paired, 

 ornamented; ventral setae begin about XV, dorsal about XXIV. Nephridiopores begin 

 about XV and open in front of lateral setae. Clitellum, XV-XXIV. Male pores on 

 XX. Septa, V/VI (the first)-VII/VIII, IX/X-XIII/XIV, thickened; VIII/IX absent. 

 Gizzard in V ; calciferous glands in IX- Spermathecae in VII and VIII, the posterior 

 pair larger. Hah. — Puerto Cabello. \ ' 



This species is provided with a series of paired papillae on segments xvii-xix 

 and xxi-xxiii. 



Genus Anteus, Peeeibe. 

 Syn. Hypogaeon, Schmaeda (in part.). 



DEPINITIOBT. Setae paired, ornamented. Clitellum, XJII (XIV)-XXIII (XXXII). 

 Nephridiopores in front of outer setae. Nephridia of anterior segments 

 differing slightly in character from those of posterior segments. Calciferous 

 glands two or three pairs. Sperm-sacs, two pairs in XI, XII. Spermathecae 

 absent. 



I have already discussed (p. 634) the differences which serve to separate the 

 present genus from Mhinodrilus. The genus certainly contains two distinct species, 

 and I am inclined to allow three. The two species, Anteus gigas and A. heterostichon, 

 are plainly separable; if A. gigas has closely-approximated setae throughout the 

 body^, the species described by Hoest (6) as A. gigas is not identical with the species 

 so named by Peeeiee. For the former I have suggested the name of A. horsti ; it 

 serves to connect the two other species, for its setae become slightly, separated from 



' This is what Peebieb says on the matter (3, p. 52) : ' Les soies sont disposes, comme chez le lombric 

 ordinaire, en quatre rangees de paires. . . Ces rang^es sont constamment parallMes d'une extremity k 

 I'autre du corps, et les soies de chaque paire sont toujours trfes-rapproch^es Tune de Tauti-e.'
