UVIGERINA SCROBICULATA, new species. 



Description. — Tost elongate, polygonal, early chambers generally 

 triserial in a three-sided test; the angles rounded, latter half of the test 

 triserial and tapering toward the apertural end; last-formed chamber 

 and sometimes the one preceding somewhat distinct from the general 

 mass of the test, triangular at the base, and broadest thence tapering 

 rapidly to the aperture, which is rounded with a slight tubular neck 

 and a very slightly developed phialine lip; sutures distinct but not 



greatly depressed, surface smooth except for 

 a finely scrobicu] ate condition, due to numer- 

 ous irregular pittings of the surface; color 

 yellowish- or brownish-white. 

 Length up to 1.5 mm. 

 Distribution. — Type-specimen (Cat. No. 

 16057, U.S.N.M.), from Albatross station 

 D5333, in 310 fathoms (567 meters), Mindoro 

 Strait, where the species is common. 



This has some of the characters of Zh angu- 

 losa and U. scJiwageri but is distinct from 

 either. The almost fusiform shape, broad- 

 est in the middle and tapering toward 

 either end with the generally triangular section, both of the whole 

 test and of the chambers with the finely scrobiculate surface, will 

 distinguish it.
