Our specimens may belong to this species described from the Pleisto- 

 cene of Timms Point, near San Pedro, California, and recorded from 

 the Eocene of Mexico. As shown in our figures the form is somewhat 

 variable, the elongate costae extend forward along the neck and are some- 

 what variable in number.

Distribution. — Stations 4 through 1246 are off the Channel Islands 

 with a depth of 6 to 240 fms. Stations 226 through 2169 constitute nu- 

 merous records off the coast of Mexico and in the Gulf of California 

 with a depth range of 10 to 200 fms. Stations 331 through 543 off Cen- 

 tral America, Galapagos Islands and South America show a depth range 

 of 7 to 50 fms. Station 653 places this species also at Kobe, Japan, in 

 45 fms. 



Lagena cf. striata (d'Orbigny) 

 Plate 47, Figs. 1-4 



The series of specimens figured on our plate shows a considerable 

 amount of variation but in general seems to come within the limits of 

 this species. Very many forms have been assigned to this species and no 

 synonymy can be given with any degree of accuracy. d'Orbigny 's types 

 were from off the Falkland Islands.
