crowded portions of the colony where, for mechanical reasons 

 probably, the zooeeia are unable to assume their typical size and 

 appearance. 



This species probably has a wide distribution on this coast. 

 It is reported by Hincks from Queen Charlotte Islands, and in 

 our collection has been obtained from the shore of Alaska, and 

 dredged at 132 fathoms off Point Loma, San Diego. It has not 

 been obtained between these localities.

Zoarium forming a delicate crust. Zoaria ovate, distinct, 

 separated by distinct lines, alternate, thickly punctured over the 

 surface, a row of small punctures outlining the margin ; orifice 

 arched above, lower margin straight with a characteristic loop- 

 like sinus in the middle (pi. 19, fig. 42) ; peristome slightly raised. 

 Auicularia none. Ooecia prominent, taller than broad, smooth, 

 convex, granular. 



The species here identified as S. cecili lacks the smooth umbon- 

 ate process described by most observers. Waters ('79) describes 

 a species from the Bay of Naples which possesses an imperforate 

 area below the aperture, and points out that this species occurs 

 in the Eed Sea and from Kino Channel, Japan, in which neither 

 imperforate area nor umbo are found. He remarks that we may 

 consider that there is a variety with an umbo and one without. 



S. cecili is not found in great abundance. A single specimen 

 is reported by Hincks from Queen Charlotte Islands. Only a 

 single small piece of a colony growing over sponge occurs in our 

 collection from San Pedro, California.
