CAULOPHACüs lotifoliu:m. 87 



Here let me give the description of the only sepcies that has 

 as yet been obtained in tlie Sagami Sea. 



CAULOPHACUS LOTIFOLIÜM. N. sp. 



PI. YII. 



This species is founded on a unique specimen which was 

 obtained by Kuma from a depth of about 572 m. (313 fms.) in 

 Maye-no-Yodomi, Sagami Sea. It passed into the possession of 

 Me. Alan Owston, while a small piece cut from it and thrown 

 into alcohol on the spot was sent to me by the collector. The 

 specimen, well preserved in the dried state, was subsequently 

 purchased by Dr. Lampert of the Kgl. Naturalien Kabinet in 

 Stuttgart, in which institution it is now preserved. 



In general shape and appearance the type specimen (PI. VIL, 

 fig. 1) reminds one of a drooping lotus-leaf; hence the specific 

 name. The apex of the inverted-conical body is continued below^ 

 into a long crooked stalk. The latter expands at the lower end 

 into an irregular basal mass, by means of which the sponge was 

 attached to a tufaceous substratum. 



If the stalk had been straight, the entire specimen would 

 have measured no less than 410 mm. in height, about three- 

 fourths of tliis measurement appertaining to the stalk. The body 

 proper measures 132 mm. across the broadest part. The stalk is 

 8-11 mm. thick in the middle part. 



As in C. eleyans, agassizi and kdus, the gastral cavity is 

 turned entirely inside out, its surface thus forming the upper 

 terminal surface of the inyerted-cQuical sponge-body. A not
