This is similar in some respects to one of Heron-Allen and Ear- 

 land's figures of Q. Icerimbatica.^^ 



Both the young and adult are very different from any of the 

 other reticulate forms of the Philippine material.

To this species are referred several specimens, which are found at 

 a number of stations, with periphery and reticulations at the sides 

 somewhat like Q. sagra d'Orbingy but not bicarinate. A study of 

 the West Indian shallow-water material, together with d'Orbigny's 

 Cuban Monograph, shows that Q. reticulata in the West Indies is a 

 very definite species and similar in general characters to that re- 

 ferred to here, but not including the various reticulate forms or 

 species which are referred to this name by various a,uthors. 



Typical material occurred at 15 stations, ranging in depth from 

 17 to 303 fathoms (31 to 554 meters), the average being 76 fathoms 

 (139 meters). Bottom temperatures are given at two stations; 

 these are 52.3° F. (11.2° C), and 53.3° F. (11.8° C); as both repre- 

 sent the deepest stations in the series, the average for the shallower 

 water stations woidd probably bring this up to 75° F. (23.8° C.) 

 at least. All but one of the stations are in the Ai-chipelago proper, 

 most of them in the Sulu region. It has occurred in the Sulu Archi- 

 pelago, off Jolo, off Siasi, and off Tawi Tawi; also off northern Cebu, 

 between Burias and Luzon; Verde Island Passage; and to the south- 

 ward in Buton Strait, where it occurred at 24 fathoms (44 meters), 

 showing that the species is probably widely distributed there if 

 shallow-water material were obtainable.
