and in Geoscolex maximus, “the sete in the posterior segments 
have also a tendency to separate.” 
The cltellum also is less extensive than in Anteus gigas, 
though this point is of less importance and mainly due to a 
difference in the state of maturity in the two specimens. 
Finally it comes from a different locality *. 
The following is a definition of the three species. I reserve 
the generic definition until the next section. 
1. Anteus gigas, Perrier. 
Anteus gigas, Perrier, Nouv. Arch. Mus, t. viii. p. 50. 
1 metre 16 centim. in length. Sete strictly paired. Six 
strong infundibuliform septa following gizzard.  Clitellum 
occupying segments xili—xxix. (?) Nephridia changing in 
structure in the twentieth segment. 
Hab. Cayenne. 
2. Anteus Horsti, Beddard. 
Anteus gigas, Horst, Notes Leyd. Mus. vol. xiii. p. 77. 
86 centim. in length. Colour (in spirit) bluish green, 
darker dorsally; clitellum brownish. Sete paired, becoming 
separated slightly from each other posteriorly. Clitellum 
occupying segments xiv.-xxxil. Three pairs of calciferous 
glands; six strong septa following gizzard. 
flab. Brazil. 
3. Anteus heterostichon (Schmarda), 
Hypogeon heterostichon, Schmarda, Neue wirb. Thiere, Bd. i. Hiilfte ii. 
p. 14. 
25 centim. in length. Colour (in spirit) whitish brown, 
?7. @. no pigment in skin or very little. Clitellum occupying 
segments Xv.-xxiil. Sete strictly paired anteriorly, widel 
divergent posteriorly. ‘I'wo pairs of calciferous glands. Four 
strong septa following gizzard. Posterior nephridia from 
those of segment xiii. different in structure from anterior, 
Hab, Ecuador and the Cordilleras. 
Affinities of Genus Anteus. 
Vaillant has recently proposed to unite the genera Anteus 
* I do not mention the ornamented sete, on the assumption that they 
also exist in Anteus gigas; and yet Perrier, who discovered these sete in 
Rhinodrilus, says nothing about their existence in Antews. Indeed he 
remarks on p. 145 of his memoir, when giving briefly the characters of 
the genera, that in Anteus the sete are all alike, i.e. noé modified upon 
the clitellum.
