110 HAWAIIAN AND OTHER PACIFIC ECHINI. 



Key to the Species of Neolampas. 



Mouth approximately central; genital pores 4 loveni. 



Mouth distinctly anterior. 



Genital pores 3; periproct not distinctly wider than long rostellata. 



Genital pores 2; periproct distinctly wider than long tenera. 



Neolampas loveni. 



Catopygus loveni Studer, 1880. Monatsb. Berlin Akad., Wise., p. 878. 



Nothing is known as to the pedicellariae of this species. Further material 

 may show that it is not a Neolampas at all, but there is nothing in Studer's 

 description to prevent its being placed here. The two original specimens were 

 taken in 117 fms. south of the Cape of Good Hope. 



Neolampas rostellata. 



A. Agassiz, 1869. Bull. M. C. Z., 1, p. 271. 



The miliary spines are like those of Oligopodia, with slightly swollen, 

 rather solid tips. Doderlein's figure of one (1906. Valdivia Ech., pi. 48, fig. 9g) 

 is rather indistinct but his figures of the pedicellariae (figs. 9 a-f) are satisfactory. 

 On the specimens examined I could find only ophicephalous pedicellariae but 

 they were fairly common. The valves are only about .06-.08 mm. long, aside 

 from the moderately developed loop. 



Neolampas tenera. 



De Meijere, 1902. Tijd. Ned. Dierk. Vereen, (2), 8, p. 8. 



According to de Meijere's crude figure (1904. Siboga Ech., pi. 19, fig. 389) 

 the valves of the ophicephalous pedicellariae of this East Indian species must 

 be very different from those of rostellata. No tridentate pedicellariae were 



found. 



Anochanus. 



Grube, 1868. Monatsb. Akad. Berlin, p. 178. 

 Type, Anochanus sinensis Grube, 1868. hoc. at. 



This is another monotypic genus of which very little is known for Grube 

 never published his promised monograph on it, and no one has since met with 

 the species.
