One female specimen, of a bright pink colour, in length 

 (measured from front margin of carapace to apex of telson) 99 

 millim., from Station 62, 1439 fathoms ; and one male and 

 one female specimen, of a milk-white colour, measuring 

 respectively 8-4 millim. and 82 millim., from Station 97, 

 1310 fathoms. 



Pentacheles, Spence Bate. 

 27. Pentacheles, sp. 

 A single specimen, with the chelipeds wanting, from Station 

 105, 740 fathoms. 

 Colour pale pink. 



28. ? Pentacheles (? immature). 



At Station 102, 920 to 690 fathoms, a very remarkable 

 specimen was obtained, which may best be described for our 

 present purpose as a Pentacheles with a globularly inflated 

 carapace and all the spines of its dorsal integument of larva- 

 like length and sharpness. It recalls a good deal the curious 

 larva which Spence Bate has described and figured ( l Chal- 

 lenger ' Macrura, fig. 30, after a drawing by Willemoes von 

 Suhm) under the name of " Eryoneicus emeus." We believe 

 that notwithstanding its great size — 36 millim. in length — it 

 is an immature form of some species of Pentacheles, bearing 

 to the adult form a relation similar to that which exists 

 between a just-hatched and an adult crayfish. 



Our specimen speaks to the accuracy of Willemoes von 

 Suhm's drawing of that which, there is little doubt, is only a 

 very much younger stage. 



Length 36 millim. 



Colour in the fresh state pink.
