Description. — Test lenticular, biconvex, chambers numerous, in a 

 close-coiled, generally flattened trochoid spire, of about three volu- 

 tions, each with several chambers; the sutures indistinct, as well as 

 the line of the spire, due to the great development of a supplementary 

 skeleton, only the last two or three chambers being at all distin- 

 guishable from either side; as formed these are rounded with a thin, 

 finely perforate wall; the general surface of the test very rough and 

 hispid, with short flattened spines, projecting radially and often 

 covering the spines as well; periphery of the test with a few spines 

 which are usually somewhat flattened and short, widest at the base; 

 aperture a series of pores at the base of the last-formed chamber. 



Diameter up to 2 mm. 



Brady originally described this species from among the islands 

 of the Pacific, one station at 155 fathoms (283 meters), the remainder 

 ranging from 3 fathoms (5 meters) or less to 37 fathoms (68 meters). 

 Millett gives it from the Malay Archipelago with the note: 



The examples are neither numerous or large. 



In the Philippines it occurs at the following localities: China Sea, 

 off southern Luzon; vicinity of Jolo, Sulu Archipelago; Tawi Tawi 

 Group; off Romblon; between Panay and Negros; Sogod Bay; 

 southern Leyte; between Marinduque and Luzon; Gulf of Davao; 

 between Bohol and Cebu; oast coast of Luzon; Darvel Bay, Borneo; 

 and Binang Pool, Subin Bay. 



The newly added chambers in this species are added directly on 

 top of the hispid secondary skeleton, and this is produced so rapidly 

 that rarely more than two chambers in the series retain their original 

 s"arface before being so covered. 



From the evidence of the ''planches inedites" d'Orbigny 's Calca- 

 rina quoyi seems to be the same as C. hispida H. B. Brady; but as 

 the former could not have been identified until the publication of the 

 figures by Fornasini in 1907, it must remain a synonym of C. hispida.
