clockwise, quinqueloculine series, each succeeding chamber farther 

 removed from the base; sutures depressed, distinct; wall thin, orna- 

 mented with fine, regular, longitudinal costae; aperture radiate. 



Length 0.60-0.95 mm.; breadth 0.25-0.30 mm.; thickness 0.18- 

 0.23 mm. 



Guttulina pulchella is one of a few well-defined species among the 

 Polymorphinidae described by d'Orbigny. Its slender, elongate 

 chambers, marked with regular, longitudinal costae, are its charac- 

 teristics and can not be confused with any of the other known species. 



Distribution. — D'Orbigny recorded the present species from the 

 shore sand of Cuba and Martinique. We have specimens from numer- 

 ous stations off the Dry Tortugas, near Florida, 7-18 fathoms, and 

 from Albatross D2420 off the eastern coast of the United States in 

 104 fathoms.

Test broadly fusiform, obtuse and rounded at the initial end, acute 

 at the apertural end; chambers inflated, oval, but little embracing, 

 arranged in a quinqueloculine series, each succeeding chamber rapidly 

 enlarged, removed slightly from the base; sutures much depressed, 

 distinct; wall marked by equidistant, longitudinal costae; aperture 

 radiate. 



Length 0.63-0.80 mm.; breadth 0.35-0.42; thickness 0.25-0.35 mm. 



This is a well-defined species described by H. B. Brady, Parker, and 

 Jones, and there is but little danger of confusing it with any other 

 species of the genus. 



The surface markings are very regular and distinct, although in some 

 specimens they are much finer. 



Distribution. — The original authors reported it from soundings from 

 Storm Bay, Tasmania. It is common off the eastern coast of Aus- 

 tralia. We have specimens from Albatross D5152, 34 fathoms, Sulu 

 Archipelago; D5311, 88 fathoms, China Sea, off southern Luzon, 

 P. I.; shore sand, Torquay, on Bass Strait, Victoria, Australia; shore 

 sand, Newcastle Bay, New South Wales; Van Dieman's Inlet, Gulf 

 of Carpenteria, Queensland, 10 fathoms; and Wool Bay, Yorkes 

 Peninsula, west side of St. Vincent Gulf, South Australia.
