with Todarodcs in Laving only four rows of distal tentacular suckers, 

 and in the sharp den tie illation of its large suckers. According- to Steen- 

 strup's system this would have to be made still another genus, or else 

 his generic characters would have to be entirely changed in order to 

 admit it into either of his groups. The existence of eight rows of suck- 

 ers in Illex seems to be due merely to the crowding together of the or- 

 dinary four rows ; nor can we attach much importance to the superficial 

 furrows in the siphon-groove. Therefore, my own opinion is that Illex 

 and Todarodcs should be reunited and should retain the name Omma- 

 streplies* in a restricted sense. The absence of connective suckers and 

 tubercles on the tentacular arms will be the most important diagnostic 

 character to distinguish it from Sthenotcuth is and Arch iteutli is. Dosidicus 

 is, perhaps, only an abnormal Sthenotcuth is with partially reproduced 

 arms.

Body, in the younger specimens, long and slender; in the adults, es- 

 pecially when the stomach is distended with food, and in the breeding 

 season, rather stout ; most so in the large females ; in preserved speci- 

 mens the apparent stoutness of the body depends very much upon 



* I can see no necessity for the proposed reformation of the original spelling of this 

 ■word by changing it to Ommaiostrephes, for usage justifies the elision of a syllable in 

 so long a name. The original spelling lias been unchallenged for over forty years. 



* This species is not well figured in the last edition of Gould's Invertebrates. Plate 

 25, fig. 339, which Mr. Binney refers to it, really represents a Loligo. Plate 26, figs. 

 341-344 (erroneously referred to Loligopsis pavo), was doubtless made from a specimen 

 of this species, but, if so, the long arms were incorrectly drawn, and confused with the- 

 short arms.
