Sars; finally the upper outline behind the rostrum is distinctly 

 angular at the dorsal organ. 



Localities. — Stat. 1676, 1 spécimen; stat. 171 5, 1 3 spé- 

 cimens; stat. 1749, 5 spécimens; stat. 1760, 1 spécimen; 

 stat. 1768, i3 spécimens; stat. 1794, 1 spécimen; stat. 1797, 

 2 spécimens; stat. 1800, 1 spécimen; stat. 1 856, 3 spécimens. 

 — The localities from the East-Indian archipelago are omitted. 



Remarks. — Among the différences pointed out between 

 N. microps and N. tenella those observed in the shape of their 

 eyes afford the best distinguishing character, not only in the 

 adults but even in very small spécimens. — I take it for certain 

 that the characteristic species described here is identical with 

 N. tenella, G. O. S. Sars says that none of his spécimens did 

 exceed the length of io mm ; this small size and his descriptions 

 and figures of the elongate legs and of rostrum show that they 

 were young. His fig. 5 is correct in most respects, but the shape 

 and the uniformly black colour of the eye must be incorrect 

 and is, unfortunately, misleading. 



Nematobrachion, Caïman 

 (Nematodactyhis. Caïman, olim) 



In a Note published together with the above-mentioned 

 paper of Holt & Tattersall D r W. L. Caïman discards the name 

 Nematodactyhis as preoccupied and introduces the dénomi- 

 nation quoted. The single species hitherto referred to that genus 

 must consequently be named Nematobrachion boopis, Caïman. 

 This species, which has been mentioned in my former paper, 

 is common in the area explored during 1904 : I have now seen 

 68 spécimens from 14 stations. 



It may be added that Stylocheiron Jlexipes, Ortm., according 

 to my examination of spécimens in the Copenhagen Muséum, 

 must be transferred to the genus Nematobrachion.
