By Lawrence Edmonds Griffin.' 

 (From the Zoological Laboratory, University of the Philippines.) 



DIAGNOSIS. 



Body from 13 to 20 centimeters long, not contracted behind 

 the head, sloping upward to the inhalent siphon, descending 

 abruptly behind; entirely covered with simple and compound 

 dermal processes, the largest of which may be 5 centimeters long, 

 a large dermal process between the eyes ; another is usually found 

 between the tentacles. Foot extending to posterior extremity 

 of body, sharply pointed behind, broader than body. Ground- 

 color, light gray, overlaid with yellow dots and black markings 

 so that the general effect is olive-green. 



Two or three rows of large peacock-blue spots, each surrounded 

 by a narrow brown line, extend along the back and sides of 

 the body. Anterior end of branchial fissure a little in front 

 of the middle of the body. Tentacles large, 25 to 30 millimeters 

 long; rhinophores more slender and tapering, almost as long as 

 the tentacles. Apparently this is the largest described member 

 of the genus.
