CHARACTERISTIC DEEP-SEA TYPES. — CRUSTACEA.^ 



In a rapid survey of the " Blake " collections for the sake of 

 noting some of the more interesting discoveries, the large num- 

 ber of very small and exceedingly long-legged spider-crabs 

 (Maioidea) first attract attention. Species of this general char-

Fig. 225. — Anomalopus frontalis. ^\^. (Alpli. Milne-Edwards. ) 



curvirostris (Fig. 226), are found to be numerous, and many 

 of them very abundant, at depths between 30 and 300 fathoms, 

 in the West Indian region, and a few species extend northward 

 to the south coast of New England. Fisolamhrus nitidus 

 (Fig. 227) represents another group of Maioidea inhabiting 

 similar depths. 



Among the Cancroidea (crabs and their allies), which are so
