Halichoclona gellindra de Laubenfels, 1932, p. 114. 

 Adocia gellindra de Laubenfels, 1936, p. 71. 



Diagnosis. — "Shape encrusting, size 2 to 4 mm thick, somewhat more 

 than 4 square cm in area. Consistency, fragile. Color in life, pale lavender. 

 Oscules, few and irregular in shape, about 1 mm in diameter, often with 

 raised collars nearly 1 mm high. Pores, abundant, 30 jx to 50 /x in diame- 

 ter. Surface, superficially smooth. 



"Ectosomal specialization, a crust of tangentially placed oxeas, its 

 thickness only about 20 /a. Endosomal structure, oxeas in very regular 

 isodictyal reticulation, united at their apices only. 



"Principal spicules, oxeas size 3 /x by 110 /x to 4 /a by 120 /x. The 

 specimen from Laguna Beach, California, had spicules 8 ju, by 150 /a to 

 10 IX by 170 /x." (de Laubenfels, 1932, p. 114.) 



Holotype.—\J .?,.'NM. 



Type locality. — Carmel, California. 



Distribution. — Reported from Carmel, California, to the Gulf of 

 California. 



Material examined. — 

 Sta. 728-37 San Esteban Island 3-27-37 Shore 



Remarks. — The oxea size (5 by 145 /x to 8 by 180 ^) of the Gulf 

 specimens is rather larger than the typical size found in the holotype but 

 corresponds very closely with the sizes reported from the specimens found 

 at Laguna Beach, California. 



Adocia ambrosia, new species 

 Plate 11, Figs. 21, 22; Plate 12, Figs. 23, 24 



Diagnosis. — The specimen of this sponge is 14 cm long, 4 cm wide, 

 and 3 cm thick. It is rather ramose in general form. In texture it is woody, 

 and in color a light drab when preserved. The surface is superficially 

 smooth, and there is a definite tangential dermal skeleton, nondetachable, 

 averaging 600 (x in thickness. The specimen appears to be a fragment of a 

 larger mass. 



Pores are abundantly scattered all over the surface, although they 

 are too small to be seen with the naked eye. The average diameter of these 

 openings is 30 /x.
