HYALASCUS SIMILIS no v. sp. 



Just in time to admit of the insertion of this description, 

 ]Mr. Alan Owston has shown me, with his usual courtesy, a 

 l)eautiful and excellently preserved specimen (O. C. No. 7803) 

 acquired by him not long ago from the coast of the Province of 

 Tötömi. It at first appeared to me to l)e a second specimen of 

 Hyalasciis sagamiensis, but a close study of the spiculation has 

 led me to think otherwise and I propose to call it H. similis n. 

 sj-». The exact circumstances of the capture of the specimen are 

 not known. 



The shape 

 of the specimen 

 is shown in the 

 accompanying 

 text-figure 3 in 

 one-fifth natural 

 size. The saccu- 

 lar and rather 

 thin-walled body 

 measures 380mm. 

 in total height. 

 The main part of 

 it is distinctly 

 ïcxt-fiouie 3. laterally com-
