Larger than typical meyeri ; 200 mm. or more in height. The wall projects 

 externally in a number of small or large, irregularly rounded, hillock-like or 

 tubercle-like prominences. À large quantity of diactins (liters into the com- 

 position of hypodermal strands ; otherwise of essentially same spiculatiou as in 

 typical species. 



ß. C, mcyeii var. ruyoia. 



Also larger than typical meyeri ; almost a foot in height. The wall with 

 irregular prominences, while the general surface is extremely uneven on account 

 of numerous wrinkle-like ridges. Spiculatiou as in var. tvLerom. 



19. C. pachyaciina, n. sp. 



Shape and size like C. meyeri var. tuberosa or rugosa. Sponge of rather 

 compact texture, with scanty 'narrow allèrent apertures. Both autodermalia 

 and gastralia are pentactins. Hypodermal pentactins strong, unusually thick- 

 rayed (ì mm. thick with ray length of 2:; min ). Intermedia as in G. meyeri. 



Loc. : Tosa Sea (Shikoku). 



20. C. corrugata, n. sp. 



Sponge-surface with numerous pit-like or irregular depressions leading into 

 a system of anastomosing intercanals. Through-going passage- present at the 

 junction of body with stalk, i. e., the latter divides into a number of branches at 

 the upper end. Up to about a foot in height. Autodermalia stauractins and 

 pentactins, the former predominating. Gastralia, mostly stauractins. Inter- 

 media resemble those of C. meyeri or C. padiyaetinu.
