Table of Species of Ophioglypha — continued. 



Papilla; of arm comb continued along outer ends of the largo radial shields, and on \ 

 the margin of the inserted upper arm plate. Large depressions between basal 

 under arm plates, ........ 



Basal under arm plates, beyond the second, about as long as broad, squarish, and ' 

 with water pores between them. Arms high, with swollen upper arm plates ' 

 and very small spines. Upper disk covered, in great part by a rosette of | 

 primary plates and by radial shields, ...... 



Disk covered with much-swollen lumpy plates. Genital scales wide, thick, and in 

 a single piece. Basal under arm plates longer than wide. Papilla; of arm comb 

 short, flat, close-set, and with rounded ends, ..... 



Disk plates high and excessively swollen. Upper arm plates rising in a high sharp 

 ridge. Arm spines minute, close-set, and like little blocks, 



Interbrachial space below covered by only one or two plates besides the genital 

 scales. Upper arm plates rudimentary or wanting. Tentacle pores of arm with 

 only one rounded scale, ....... 



Disk thick, and covered with thin smooth scales. No arm comb nor papilla; along 

 genital openings. Basal under arm plates, beyond the second, short and wide, . 



\ Ophioglypha multixpina. 



f 



Disk and arm plates thick, swollen, 

 and closely soldered. Mouth 

 papilla; and scales of mouth ten- 

 tacles thick, squarish, irregular, and 

 crowded. Arm spines minute, 

 with tentacle scales similar in 

 form, and standing only on side 

 arm plate, inside the pore.

 Radial shields and primary plates 

 circular and similar,

Disk rather flat and covered with imbricated scales. Under arm plates small, widely

 diminishing in size. Arm comb of papillae more or less needle-like. Arm slightly 

 flattened with spines about as long as a joint.
