REPORT OF COMMISSIONER OF FISH AND FISHERIES. [224] 
only differ widely in the condition of the eyes, but also in the nature of 
the hectocotylization of the arms, and in anatomical characters. 
To one of these groups, containing the family Sepiolidce , I propose to 
apply the name &'epiolidea. 
The other division, Sepidea, includes the families Sepidai, Loliginida 
Idiosepidcv , and perhaps Spirulidce; but the latter might, perhaps, be 
best placed with several fossil forms in a division of which it is the sole 
surviving genus. 
SEPIDEA Verrill. 
The integument extends entirely over the eye, and there is a pore in 
front of it. Pupil crescent-shaped. Body commonly elongated. Pen 
various, rarely absent, usually large, broad-lanceolate or ovate, either 
horny or calcareous (spirally coiled, tabular, and chambered in Spirilla , 
in which it is posteriorly situated). Oue of the ventral arms of the 
male is usually hectocotylized. 
Mantle usually with three connective cartilages, rarely with one 
(dorsal) or three muscular commissures. 
Family LOLIGINIDiE. (See p. [131].) 
Loligo Lamarck. (See p. [131].) 
15. Loligo Pealei Les. (P. [132].) 
16. Loligo (Lolliguncula) brevis Blainv. (P. [ 1G1 ].) 
Sepioteuthis D’Orbig. (See p. [163].) 
Sepioteuthis sepioidea D'Orb. (Seep. [164].) 
SEPIOLIDEA Verrill. 
In this group the eye lids may either be entirely free all around, or 
the upper one may be attached to the eye-ball. Pupil either round or 
crescent-shaped. Body short, obtuse. Fius lateral, separated. Pen 
small or rudimentary, sometimes absent. Sucker-rings smooth. Dorsal 
arms, in the male, usually hectocotylized, one or both. 
Family SEPIOLlDiE. (See p. [165].)
