numerous distinct, slightly raised, longitudinal costae, the chamber 

 at the sutures continued backward along these costae giving a 

 scalloj3ed edge to the suture; aperture with a short, cylindrical neck 

 and narrow phialine lip. 



Length of microspheric form up to 2.6 mm. 



Distribution. — This species is common in the Miocene of Cali- 

 fornia. It was described from the Monterey shale, on the Ranchodel 

 Encinal, 7,000 feet south of Asuncion station, San Luis Obispo 

 County, California. The outcrop is on Graves Creek. 



Three species were described by Bagg from this material. The 

 first of these, S. hranneri, is the microspheric form of the species, 

 the other two, S. californiensis and S. elongata, represent the megalo- 

 spheric form. I have material from the type locality.

Description. — Test elongate, cylindrical, chambers of the uniserial 

 portion broader than long; sutures not deep but conspicuous; wall 

 ornamented by longitudinal costae, not close together and not 

 prominent; aperture circular with no neck but a prominent rounded 

 lip. 



Length up to 1 mm. 



Distribution.— Schwager originally described this species from the 

 Pliocene of Kar-Nicobar.^ His original figure shows a slender test 

 with an elongate neck. Recent specimens have practically no 

 neck and are stouter than the typical form. Wliether they represent 

 a new species or a variety of Schwager's species is a question. Brady's 

 specimens were of this varietal form. His records are ''off the coast 

 of South America, south of Pernambuco, 350 fathoms; shore-sand, 

 east coast of Madagascar; off Kandavu, Fiji Islands, 210 fathoms; 

 off New Hebrides, 125 fathoms; Torres Strait, 3 to 11 fathoms; off 

 Kj Islands, 129 fathoms; and off the Philippines, 95 fathoms," 

 Millett 's records are from the Malay Archipelago and Dakin's from 

 Ceylon, both probably based on Brady's figures. Egger's records 

 are dubious. I have had this varietal form from off Hawaii, 114 

 fathoms: off Guam, 234 fathoms: southeast of the Bonin Islands in
