Four specimens ; off Misaki, Sagami Sea. 



Sagami Sea ; 240 m. (Döderlein). 



The largest one of my specimens is 56 mm. across the disk, 

 which is beset with very numerous rough tubercles. One speci- 

 men (fig. c), measuring 27 mm. across the disk, closely resembles 

 the next species, almost agree- 

 ing with Lyiman's description 

 of the same, except that the 

 apparent granules, which are 

 scattered on the disk, are in 

 reality very fine, rough 

 spinules as ascertained by an 

 examination under the micro- 

 scope. A vertical section of 

 this specimen showed that it 

 had the internal structure of 

 the first type. I am inclined 

 to regard this specimen as 



possibly a natural hybrid be- ^^Q- 19- Gorgomceplialus tulerosus. a. From 



above, xl^-. h. From below, xl^. c From 



tween the typical G. iuberosus above. x2. 



and the next species, as the 



two occur almost in the same place.
