CRATEROMORPHA CORRUGATA Ijima 



Crateromorpha corrugata Ijima, Annot. Zool. Japon., vol. 2, p. 49, 1898; 

 Jonrn. Coll. Sci. Imp. Univ. Tokyo, vol. 18, art. 7, pp. 78-86, pi. 6, figs. 1-8, 

 1904. 



A small fragment of C. corjmgata was collected from a depth of 

 131 fathoms at the entrance to Enoiira, Suruga Gulf (Station 5069). 



The peculiar structure described by Ijima for Scyphidiuiri longi- 

 spina can be plainly seen in the present specimen. It also has 

 very delicate filaments, arranged irregularly, in brushlike bunches.

There is a single specimen in the collection that may be identified 

 as L. pupa. It was collected from a depth of 153 fathoms in Kago- 

 shima Gulf (Station 4934), and seems to be the largest of the species 

 hitherto recorded. It is cup shaped in form, 51 mm in height, and 

 S5 mm in breadth at the widest part of the entire stock. It has also 

 a short stalklike basal region measuring 8 mm in breadth at the 

 middle. The dermal surface is quite smooth and not covered by a 

 veil, as in the Sagami Sea specimens recorded by Ijima. 



Spiculation. — Toward the stalklike base of specimens from the 

 Sagami Sea the hypodermal lattice becomes unnoticeable. In the 

 present specimen it is irregularly distributed, and has somewhat 

 stronger-rayed pentactins with a shorter proximal ray. The pen- 

 tactins of this specimen do not protrude through the dermal layer, 

 so that the surface of their paratangentials is quite smooth. Occa- 

 sionally there occur in the hypodermalia stronger and larger diac- 

 tins, which measure 3.5 mm long and lOO/i thick at the middle. In 

 the stalklike basal region of the sponge they attain a length of about 

 5 mm. 



The parenchymal oxyhexactins supporting the skeleton of the 

 sponge may attain larger dimensions; the axial length frequently
