"Test short, thick, fusiform, lower half conical, tapering abruptly 

 from the short initial end, later half triangular, with slightly concave 

 sides ; chambers few, the last three composing one-half of the test, slightly 

 inflated; sutures distinct, not depressed, of clear shell material; wall 

 smooth, very finely perforate; aperture situated at the end of a fairly 

 short neck with a phialine lip. 



"Length of the type specimen, 0.45 mm ; diameter, 0.28 mm." 



The original description of this species from the Pleistocene of Cali- 

 fornia is quoted above. The species occurs rather rarely at numerous sta- 

 tions as follows: 1, 73, 134, 249, 1017, 1018, 1050, 1061, 1062, 1064, 

 1100, 1111, 1113, 1114, 1118, 1138, 1143, 1144, 1145, 1152, 1153, 

 1155, 1156, 1157, 1160, 1163, 1165, 1166, 1167, 1168, 1170, 1171, 

 1172, 1186, 1192, 1193, 1194, 1195, 2165, 2169. 



A. baggi and A. hughesi occur usually together and seem to grade 

 into one another. They may be merely stages or micro- and megalospheric 

 forms of a single species; A. baggi being the early stage or the megalo- 

 spheric form, and A. hughesi the adult stage or microspheric form. The 

 separation between the two seems to be arbitrary and is based on shape of 

 test (short, fusiform, and periphery not lobulated in baggi) and sutures 

 (not depressed in baggi). 



Distribution. — With the exception of one record off Isla Partida, 

 Mexico, in 140 fms, the other localities are off the Channel Islands in TZ 

 to 160 fms.
