DESCRIPTIONS OF GENERA AND SPECIES 651 



beginning on XIV, open . in front of and a little above ventral setae. Clitellum, 

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

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

 Gizzard in VI ; calciferols gland,* in XII ; intestine begins about XV, with well- 

 developed typlilosole. Last heart in XII. Halt. Passofnndo, Brazil. 

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



(2) Tykonus appuni (MICHAELSEN). 

 Anteus Appuni, MICHAELSEN, ibid., p. 218. 



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. Hob. Puerto Cabello. 

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



and xxi-xxiii. 



Genus ANTEUS, PESKIER. 



Syn. Hypogaeon, ScHMARDA (in part.). 



DEFINITION. Setae paired, ornamented. Clitellum, XIII (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 Rhinodnlus. The genus certainly contains two distinct species, 

 and I am inclined to allow three. The two species, Anteus ;/igas and A. heterostichon, 

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

 body 1 , the species described by HORST (6) as A. gigas is not identical with the species 

 so named by PERKIER. 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 



1 This is what PERKIER says on the matter (3, p. 52) : ' Les soies sont disposers, comme chez le lombrio 

 ordinaire, en quatre rangees de paires. . . Ces rangees sont constamment parallfeles d'une extremity K 

 1'autre du corps, et les soies de chaque paire sont toujours tres-rapprochees 1'une de I'autre.'
