and in Geoscolex maximus, "the setae in tlic posterior segments 

 have also a tciulency to separate." 



The cUteUam also is less extensive than in Anteus girjas^ 

 though tills point is of less importance and mainly due to a 

 diti'erence in the state of maturity in the two specimens. 

 Finally it comes from a different locality*. 



1'he following; is a definition of the three s])ecics. I reserve 

 the generic definition until the next section. 



1. Anteus gigaSj Perrier. 

 Antetis giffm, Penier, Nouv. Arch. Mus. t. viii. p. 50, 



1 metre 16 eentim. in length. Setaj strictly paired. Six 

 strong infundibuliform septa following gizzard. Clitellum 

 occupying segments xiii.-xxix. (?) Nephridiu changing in 

 structure in the twentieth segment. 



Hah. Cayenne. 



2. Anteus Ilorsti, Beddard. 

 Anteits gif/as, Horst, Notes Leyd. Mus. vol. xiii. p. 77. 



86 eentim. in length. Colour (in spirit) bluisli green, 

 darker dorsally ; clitellum brownish. Setaj paired, becoming 

 separated slightly from each other posteriorly. Clitellum 

 occupying segments xiv.-xxxii. Three pairs of calciferous 

 glands; six strong septa following gizzard. 



llah. Brazil. 



3. Anteus heterostichon (Schmarda). 



ITypoqaxm lieterostuhon, Schmarda, Neue wirb. Thiere, Bd. i. Ilalfte ii. 

 p. 14. 



25 eentim. in length. Colour (in spirit) whitish brown, 

 {. e. no pigment in skin or very little. Clitellum occupying 

 segments xv.-xxiii. Seta? strictly paired anteriorly, widely 

 divergent posteriorly. Two pairs of calciferous glands. Four 

 strong septa following gizzard. Posterior nephridia from 

 those of segment xiii. different in structure from anterior. 



Hub. Ecuador and the Cordilleras. 



Affinities of Genus Anteus. 



Vaillant has recently proposed to unite the genera yln^fj/s 



* I do not mention the ornamented setae, on the assumption that they 

 also exist in Antem gujas ; and yet I'errier, who discovered these sKa3 in 

 It/imorInlu,<, says nothing about their existence in Antevs. Indeed he 

 remarks on p. 145 of his memoir, when giving briefly the characters of 

 the genera, that in Anteus the settij are all alike, i. e. not modified upon 

 the clitellum.
