Specimens with the projecting slender neck and the acute marginal 

 carinae typical of this species were found at a few stations, but 

 never in any quantity. Of the seven stations at which this species 

 is recorded the depth ranges from IS to 148 fathoms (33 to 271 

 meters), the average being 61 fathoms (112 meters). Bottom 

 temperature was given for the deepest station 54.4° F. (12.4° C); 

 none of the others are given. Tlierefore the average would be much 

 above this figure. The localities are as follows: China wSea, off 

 southern Luzon ; Sulu xVrchipelago, off Tawi Tawi; vicinity of Rom- 

 blon; off eastern Panay; off northern Cebu; Gulf of Davao; and 

 China Sea, off Formosa. Specimens were frequent at two of the 

 shallower stations and rare at the others. Hei;on-Allen and Earland 

 record it "not widely distributed, but verv fine and typical examples 

 occur at several stations, though not in any numbers." They also 

 mention that the form figured b}^ Brady*" '' represents a type which is 

 of much more frequent occurrence (than d'Orbignj^'s type) in tropical 

 gatherings, having long, narrow chambers with little curvature, 

 produced tubular neck, and strong, acute, marginal, facial carinae." 

 This evidently is the same as the form that we have had from the 

 Philippines.

This species, of which abundant specimens appear at some sta- 

 tions, seems to be well characterized. Schlumberger revived this
