Variety differing from the typical form in the ornamentation of the 

 chambers consisting of numerous, low, longitudinal costae, not continu- 

 ous across the sutures, and usually lacking on the last-formed chamber 

 or two. 



From the type specimens of this variety one would judge it to be a 

 more slender, delicate, and thinner-walled form than the species. The 

 present large collection available, however, shows it to be quite as robust 

 and heavy as the unornamented species. But, like the species, it also 

 exhibits considerable variation in size and shape of test as well as in degree 

 of ornamentation. 



This species was described from Albatross H 1805, off the west coast 

 of Mexico, Lat. 18° 33' 30'' N., Long. 114° 44' 00" W., 1732 fms. 

 Typical specimens occur at the following stations: 242, 284, 299, 412, 

 517, 1078, 1110, 1112, 1147, 1186, 1190, 1194, 1198, 1207, 1221, 2005, 

 2009, 2010, 2063, 2064, 2065, 2097, 2100, 2102, 2140, 2145, 2149, 

 2158,2163. 



Distribution. — All of these stations are off the Channel Islands and 

 in the Gulf of California in depths from 2 to 600 fms. 



Angulogerina carinata Cushman, var. vana Todd, new variety 

 Plate 35, Fig. 10 



Variety differing from the typical form in the ornamentation; the 

 carinae being thin and broad, sharp, and undulating or spinose, and 

 the walls of the early chambers covered by a few, heavy, short, irregular 

 costae or more thickly covered by finer, higher costae, often with back- 

 wardly-projecting spines. In size and shape of test and opaque wall the 

 variety closely resembles the typical form. 



Holotype (AHF no. 63) from Station 1103. It also occurs at the 

 following stations : 227, 230, 284, 1083, 1095, 1103, 1116, 1117, 1168, 

 1178, 1212, 1222, 1244, 2070, 2144, 2161.
