Description. — -Test much elongate, slender, somewhat compressed; 

 sides nearly parallel but tapering rather quickly to a blunt point at 

 the apical end, apertural end obliquely truncate; chambers numerous, 

 high, somewhat inflated; sutures shghtly depressed; wall calcareous, 

 the apical portion with fine longitudinal costae, the apertural end 

 smooth; aperture oval, in some specimens, where a uniserial condition 

 is attained, remote from the border and subterminal, otherwise reach- 

 ing to the preceding chamber as also in the young; color white. . 



Length up to 1.20 mm. 



Distribution. — This species is recorded from about the British 

 Isles, in the Mediterranean, the , Arabian Sea, and Indo-Pacific. 

 There are no records for it in the western Atlantic, the Gulf of Mexico , 

 or Caribbean, and I have failed to find anything corresponding to 

 it in all the material I have examined from this region. What few 

 specimens I have seen from European waters seem to be, as noted by 

 Heron- Allen and Earland (1913, p. 64), ''a striate form of B. punc- 

 tata.'' Most of the specimens that I have seen from the Pacific, 

 however, are of a different character, usually having the aperture 

 terminal, much as figured in the Challenger Report by Brady. In 

 this connection it is interesting to note that the original of Brady's 

 plate 53, figure 14, came from the Philippines. I am indebted to 

 Capt. F. O. Potts of Cambridge for this information, 



BOLIVINA PLANA (d'Orbigny) (?) 



Textilaria plana d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 263, No. 14. 



There are a very few specimens from off the coast of New England 

 in cold water which are thickened in the middle, and may doubt- 

 fully be referred to this species.^* This does not occur with typical 

 B. dilatata or any other of the broad forms, and just what it may be 

 must be left until more abundant specimens are available.
