FORAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 331 



The stations range in depth from 10 to 50 fathoms (18 to 91 me- 

 ters), the average being 34 fathoms (62 meters). It is therefore in 

 this region a species of comparatively shallow water. Brady's rec- 

 ords were 95 fathoms (174 meters), Philippines, and 17 to 155 fath- 

 oms (31 to 283 meters) off New Guinea. In the Atlantic, however, 

 Brady records it from much deeper water — 435 fathoms (796 meters), 

 off Bermuda, and 1,000 fathoms (1,829 meters) west of the Azores. 

 It will be interesting to see if these are really identical forms in all 

 their characters with the more shallow-water Indo-Pacific species.

PULVINULINA PHILIPPINENSIS, new species.

Pulvinulina hauerii (part) H. B. Brady (not d'Orbigny 1846), Rep. Voy. Chal- 

 lenger, Zoology, vol. 9, 1884, p. 690, pi. 106, fig. 7 (not fig. 6). 



Description. — Test rounded, composed of about three coils, the 

 outer one consisting of five chambers, very rapidly increasing in size, 

 the last-formed chamber in the adult making up nearly half the vol- 

 ume of the test; periphery very broadly rounded; dorsal and ventral 

 sides slightly rounded; sutures distinct, but not deep on the dorsal 

 side, somewhat deeper on the ventral side; slightly umbilicate; 

 wall smooth, very thin, punctate. 



Diameter 0.4 to 0.6 mm. 



Distribution. — ^Type specimen (Cat. No. 15760, U.S.N.M.) horn. Alba- 

 tross station D5268, Verde Island Passage, 170 fathoms (311 meters). 



It also occurs at the following stations: D5178, off Romblon, 78 

 fathoms (143 meters); D5381, Ragay Gulf, Luzon, 88 fathoms (161 

 meters); and D5565, between Jolo and Tawi, Tawi, 243 fathoms (445 

 meters). 



Brady refers this species to P. Jiauerii d'Orbigny, but comparison 

 with that figured by Brady shows that the two are very distinct. 

 Brady records it from seven stations in the South Pacific. It is very 

 constant in its characters and seems to be a well-defined species of 

 this general region.
