[April 2,, 1884 



belonging to the genera Polycheles, Wllmoesia, were 

 from depths of from 4000 to 5000 metres, and the won- 

 derful transparency of the forms permitted the whole 

 internal viscera to be distinctly seen. Some species of 

 Pentacheles were evidently allied to the fossil forms of 

 Eryon. 



Of the Crustacea belonging to t'le group of Macrura, 

 the one to which the crayfish and shrimps belong, miny 



were taken at very great depths. Off the Cape Verd 

 Islands, from a depth of 500 metres, a thousand indi- 

 viduals of a new species of Pandalus were taken. 

 Among the most remarkable of all of these forms is the 

 one which, through the courtesy of the editor of I.ii 

 Na/i/ri', from which journal this notice is in part trans- 

 lated, we are enabled to give the accompanying illustra- 

 tion. Named A'<-i>i,it,-i,-,iri-/iii/s f^i-tii-i/ipi's by Alphonse 



-/7;/,i (A. M. VAn- ), 



Milne-Edwards, it was, when taken fresh from a depth 

 of 850 metres, of a splendid rose colour. The extreme 

 length of its antennae will at once attract attention, and 

 tno less remarkable are the wonderfully attenuated feet, 

 of which the third, fourth, and fifth pairs are longer than 

 the first and second. The eyes are large, but the eye- 

 stalks are not elongated. In another member of this group, 

 Clypliiis ?iiii>-sii/>!a/!S, the finiale had the lateral portirms 



of the abdominal segments developed so as to form a 

 pouch-like receptacle, in which the eggs were deposited. 



Wlien trying to draw conclusions from the phenomena 

 presented by the numerous forms of Crustacea collected 

 during the Talisman cruise, one is struck by the strange 

 diversity in these phenomena. While some of the species 

 are blind, others have well-developed organs of vision ; 

 while in some the eye-stalks are flexible, in others they
