54 BULLETIN 71, UNITED STATES NATIONAL MUSEUM. 



Description. — " Subglobular, with coarsely tuberculated surface; 

 wall thick, obsoletely cavernous, the chamber somewhat irregular, 

 showing faint traces of subdivision; color gray or whitish; the con- 

 sistency of the shell is usually 

 loose, the texture being finely 

 arenaceous, with a large portion 

 of shell debris. Diameter 1-2 

 mm." 



Distribution. — Goes found and 

 described this species from ma- 

 terial from two Albatross sta- 

 tions D3415, in 1,879 fathoms 

 off the west coast of Mexico and 

 D3407, in 885 fathoms, near the 

 Galapagos Islands. 



The above description is cop- 

 ied from that of Goes. Hisspec- 



stations I have examined. There are six, rather poorly characterized 

 specimens, more irregular than his figure. One of these specimens is 

 figured here. 



CRITHIONINA LENS Goes. 



Crithionina lens Goes, Bull. Mus. Comp. Zool., vol. 29, 1896, p. 24, pi. 2, figs. 

 5-8.— Rhumbler, Arch. Protistk., vol. 3, 1903, p. 232, fig. 60 (in text). 



Description. — Test flattened, orbicular, elliptical or irregular in 

 outline, thickest in the middle, giving a lens form to the test as a 

 whole ; interior with a central chamber and many large radial cham- 

 berlets irregular in number, size and shape, central cavity sometimes 

 indistinct or obsolete; wall thick, composed of sponge spicules and 

 fine amorphous matter with very fine sand; color light gray, often 

 almost white. 



Diameter 2-4 mm. 



Distribution. — Goes records this species from three stations in the 

 eastern tropical Pacific, one off Acapulco, Mexico, another south of 

 Panama, the third near the Galapagos Islands, Albatross stations 

 D3376, D3407, D3419, in 772-1,132 fathoms. This is the only region 

 where this species has been met with. I have found a single poor 

 specimen from station D4334, off San Diego, California.
