Distribution. — These studies record this species as far north as the 

 South Farallone Island, San Francisco, California, in 38 fms. ; as far 

 south as Gorgona Island, Colombia, in 32 fms. A single record for 

 the Galapagos Islands is Cartago Bay, Albemarle Island, in 12 fms. 

 Numerous localities off southern California and Mexico have this 

 species. In the Gulf of California it has been recorded as far north as 

 San Pedro Nolasco Island, in 32 fms. 



Reophax scorpiurus Montfort (?) 

 Plate 2, Fig. 13 



Under this species have been placed very many elongate and irregu- 

 lar forms of Reophax. Brady's figures in the Challenger Report assigned 

 to this species cover a wide range of form and building materials in the 

 tests. There are numerous specimens in our collections ranging from 

 the very coarse test figures (PI. 2, Fig. 13) to those of pure sand grains. 

 It is difficult to tell how much of the variation is due to the difference 

 in the kind of ocean bottom and how much due to the selective power 

 of the animal itself. It has seemed best, therefore, to leave this some- 

 what heterogeneous series under this name. Localities: 79, 215, 223,

 2032, 2034, 2054, 2066. 



Distribution. — The numerous station records indicate a range as 

 far north as Point Pinos, California, and as far south as Gorgona 

 Island, Colombia, in shallow waters.
