From the original figure given by Schwager this recent form would 

 seem to be distinct in the large aperture which is without a neck, the 

 chambers low and broad, while the figure given by Schwager shows a 

 typical Uvigerina aperture, the neck long and slender and the cham- 

 bers as long as broad and much more inflated. I am inclined to 

 think that our recent species figured here is distinct, but more mate- 

 rial is necessary to establish this view.

Siphogenerina costata Schlumberger, Feuille des Jeunes Naturalistes, ann. 13, 

 1883, p. 118, fig. 13. 



Description. — Test elongate, cylindrical, or tapering, chambers of 

 the uniserial portion broader than long; surface marked by several 

 rather widely separated, well-developed costae, each extending nearly 

 the length of the test and not affected by the sutures; aperture typ- 

 ically with a short tubular neck and well-developed flaring lip. 



Length 0.5 to 1 mm. 



Distribution. — Brady records the occurrence of this species from off 

 the Philippines in 95 fathoms, off the coral reefs of Honolulu, Hawaiian 

 Islands, in 40 fathoms and in the volume of the Challenger "Report 

 on the Summary of Results," from station 232 in 345 fathoms on the 

 Hyalonema-ground southeast of Japan. I have material from Alba- 

 tross stations off Japan in this same region, D4916 in 361 fathoms and 

 D4807 in 44 fathoms. It occurs also at Nero station 1306, between 

 Yokohama and Guam, in 1,208 fathoms, and Nero station 2071 in 

 271 fathoms near the Hawaiian Islands. The only temperature 

 records are from D4916, where the bottom temperature was 42.7°. 



Both megalospheric and microspheric specimens were seen and fig- 

 ured by Brady, who notes the much larger size of the latter. The 

 form, too, is different, the microspheric form being much more tapering. 



SIPHOGENERINA STRIATULA, new species. 



Plate 47, fig. 1. 



Description. — Test elongate, subcylindrical ; chambers for the most 

 part broader than long, but the terminal one nearly as long as broad; 

 sutures slightly indented; surface ornamented with fine longitudinal 

 striae; aperture narrowly elongate, without a neck, but a well- 

 developed lip present. 



Length about 1 mm.
