from each of which single specimens were obtained. The stations 

 range in depth from 25 to 241 fathoms (46 to 441 meters), with 

 the average 93 fathoms (167 meters) and the bottom temperatures 

 were given from 51.3° to 76.3° F. (10.7° to 24.6° C), with the average 

 57.1° F. (13.9° C). 



At two stations — D5133 in 38 fathoms (70 meters), Sulu Sea, off 

 western Mindanao, and D5220 in 50 fathoms (91 meters), between 

 Marinduque and Luzon — it was abundant. At other stations it was 

 frequent or represented by few specimens. 



Specimens seem to be rather larger than the measurements given 

 for this species, running up to over 2 mm. in well-developed speci- 

 mens. 



This is a very strikingly ornamented species, of large size, and 

 excellently figured by Brady. For that reason the lack of records 

 is significant. Brady's original records were from off the Philippines 

 in 95 fathoms (174 meters); off the New Hebrides, 125 fathoms (229 

 meters); and the coast of Korea, 10 to 50 fathoms (18 to 91 meters). 

 In the North Pacific work I added two records for the species off 

 Japan in 66 and 39 fathoms (121 and 71 meters). The Philippine 

 records complete what is known of its distribution. 



It is not recorded by Millett from the Malay Archipelago, by Dakin 

 from Ceylon, by Heron-Allen and Earland from Kerimba, by any 

 writers from Australia, nor by Egger from any of his material. 



Its fine development in the Philippines shows that it is a char- 

 acteristic species, and we must come to the conclusion that it is a 

 species of comparatively limited distribution.
