spicules employed are invariably of a simple type, and this is very noticeable in the 

 Cebu specimens, as hexactinellid spicules abound in that dredging, 



Heron-Allen and Earland, in describing this species, had material 

 from off Cebu; I have failed to find any specimens in the Philippine 

 material I have had. 



NOUniA COMPRESSA Heron-Allen and Earland. 



Nouria compressa Heron-Allen and Earland, Trans. Zool. Soc. London, vol. 20, 

 pt. 12, 1914, p. 378, pi. 37, figs. 21-26. 



The original description of this species is as follows : 



Test free, highly compressed, consisting of 2 to 5 chambers rapidly increasing 

 in size and arranged biserially, the walls of the test consisting of a single layer of sponge- 

 spicules neatly cemented together into a smooth and finished surface. A grain of 

 sand or glauconite is occasionally used to fill in a crevice between spicules (figs. 22 & 

 25). Marginal edges acute and usually smooth and unbroken, especially at the oral 

 extremity of the shell. Less neat at the aboral end, where there is often a marginal 

 fringe of projecting spicular points. Sutural lines nearly flush and obscure, but 

 generally well marked, owing to the divergent angles at which the spicules are arranged 

 in adjacent chambers. Aperture a neatly constructed terminal slit, sometimes with 

 a slightly raised border or lip of cement (figs. 21, 23). Internal septa constructed of 

 spicules and very often incomplete. 



This species, described by Heron-Allen and Earland from the 

 same station off Cebu, in 120 fathoms (220 meters), did not occur in 

 any of the Philippine material I have had, but I have had very typical 

 specimens from off the coast of Japan.

This species, originally described from the coast of Japan, has oc- 

 curred at a single station, D5420, between Cebu and Bohoi, 127 

 fathoms (233 meters); bottom temperature, 59.0° F. (15° C). 



The Philippine specimen seems to be tj^pical.
