 Miliolina tricarinata, var. terquemiana Chapman, .Tourn. Linn. Soc. Zool., vol. 28, 



1900, p. 174. 



The only specimens which can be referred to this species are like 

 the inflated form figured by Heron-Allen and Earland from the 

 Kerimba Archipelago. From the records this species seems to be 

 decidedly Indo-Pacific in its range. 



The only station at which it occurred is D5154, Sulu Archipelago, 

 Tawi Tawi Group, in 12 fathoms (22 meters).

Triloculina insignis Cushman, Bull. 71, U. S. Nat. Mus., pt. 6, 1917, p. 72, pi. 27, 

 fig. 3. 



There are rare specimens from Albatross station D5141, off Jolo, 

 29 fathoms (52 meters), and D5236, Pacific Ocean, east coast of 

 Mindanao, 494 fathoms (903 meters), which may be referred to this 

 species. 



There seems to be a mixture of forms in the material described 

 by Brady. In the Challenger Report (pi. 4, fig. 8) is evidently a 

 triloculine form of Biloculina comata Brady, as shown by the form 

 of the aperture. Some such specimens are often found where B. 

 comata is abundant. Brad}^ has a single North Pacific record from 

 deep water for this species. This may have been the form of B. 

 comata which he figures. Flint *^ figures a form (pi. 45, fig. 2) and 

 has it from the same station from which he reports B. comata, and 

 the two probably represent the same species.
