This species was described from Albatross station D4900, off the 

 southern portion of Japan, where numerous subtropical species seem 

 to reach their northern limits. It is not surprising therefore to find 

 as in other cases that this species occurs frequently in the Philippine 

 region. It has occurred at numerous stations well scattered through- 

 out the region ranging in depth mostly from 118 to 700 fathoms 

 (203 to 1,280 meters), with two stations less than 100 fathoms (183 

 meters), with depths of 78 and 14 to 25 fathoms (143 and 25 to 46 

 meters), with the average 293 fathoms (53G m.eters). The bottom 

 temperatures range from 50.4° to 57.4° F. (10.2° to 14.1° C), with 

 the average of 52.5° F. (11.3° C). This is close to the bottom tem- 

 perature of the original station, which was 52.9° F. (11.6° C). 



The Philippine specimens are not as large as those from southern 

 Japan, but many of them are nearly 10 mm. in length and have the 

 characteristic form. The localities are off Romblon; off western 

 Bohol; between Marinduque and Luzon; China Sea, oft' southern 

 Luzon; off Hongkong, and off Formosa; off Palawan, Jolo, and 

 Tawi Tawi; and to the south near Patiente Strait; and in the Gulf 

 of Boni.
