FOEAMINIFERA OF THE PHILIPPINE AND ADJACENT SEAS. 459 



Returning to the Challenger Report (pi. 4, fig. 10) refers to a dif- 

 ferent species and may be taken as the type of T. insignis. This 

 is a striate form of the T. trigonula group, and apparently found in 

 shallow water tropical regions. It may be suggested that the form 

 figured by Heron-Allen and Earland from Kerimba (pi. 41, figs. 29, 

 31) is the inflated form of T. terquemiana, and may really be this spe- 

 cies, which is very similar to ClialUnger (pi. 4, fig. 10), noted above.

This usually common species occurs at but five stations, and is 

 not common at any of them. These range in depth from 61 to 494 

 fathoms (112 to 903 meters); bottom temperatures range from 

 41.2° F. to 56.4° F. (5.1° C. to 13.5° C). 



These few stations are east of Masbate Island; Pacific Ocean, east 

 coast of Mindanao; Palawan Passage; between Samar and Leyte; 

 and off Jolo.
