CKUSTACEA OP TEAKZ-JOSEF LAND. 61 



Orders — Podophthalma (or Stalk-eyed Crustacea) and Ebeioph- 

 THALMA (or Sessile-eyed Crustacea). The first was represented 

 in Mr. Bruce's collection by seven species, five of wliicli belong to 

 tbe smaller Macrura and two to the Schizopoda : there were no 

 representatives o£ the larger Brachyura in the collection. But 

 if the Stalk-eyed Crustacea are few in number, the Sessile- 

 eyed forms are fairly numerous : they comprise Cumacea, of which 

 there are five species ; Isopoda, represented by twelve ; and 

 Amphipoda, of which there are forty-six species. 



(2) The Entomosteaca. 

 The Entomostraca are divided into three Orders, but the first 

 of these, BraGhiopoda, is_^not represented in the collection ; there 

 are, however, numerous examples of Ostracoda and Copepoda. 

 Thirty-four species of the former and sixty-six of the latter, 

 with one new variety, have been obtained, and are recorded in 

 the sequel. 



(3) The Thteosteaca or Cireipedia. 

 The only Cirripedia found in the collection are two species of 

 Barnacles, both of which are widely distributed in the northern 



seas. 



Perhaps the preceding statements may be more clearly under- 

 stood if put into tabular form, thus : — 



Table showing the general classification and number of the 

 species of Crustacea contained in Mr. Bruce's Collection of 

 Crustacea from Eranz-Josef Land.
