is 84^"^ long, exclusive of the arms ; the body is 72™°^ long, 15'"°^ broad ; 

 the caudal fin is 25°^"^ long and 36"^°^ broad. 



A fresh specimen, caught in Casco Bay, had the following propor- 

 tions : Length of head and body, not including the arms, 221'""^ ; length 

 of caudal fin, S6'''''' j breadth of fin, 90"^"^ ; diameter of body, 35"^"^ f 

 length of upper arms, 80"^^ ; of second pair, 100"^^ ; of third pair, 100°^°^ 5 

 of extensile arms, 182™"^ ; of the ventral pair, 90"^"\

Ommastrephes Bartrcunii (Lesueur, sp.) is found in the Gulf Stream off 

 our coasts, and may sometimes occur accidentally on our shores. It is 

 a more slender and elongated species than the preceding, with a rela* 

 tively shorter caudal fin. It is also darker colored. The figure given 

 by Biuney in the last edition of Gould's Invertebrata of Massachusetts 

 (Plate 25, fig. 310) does not represent this species.

South Carolina to Massachusetts Bay. Yery common in Long Island 

 Sound and Yineyard Sound. 



The young, from an inch to two inches in length, were taken from the 

 middle of July to the last of August in great numbers, at the surface, 

 in Yineyard Sound, by Mr. Yinal N. Edwards.

This is probably identical with the preceding species. The slight 

 differences noticed are probably sexual, but as I have not been able to 

 fully satisfy myself in regard to this, I have not thought it proper to 

 unite them at this time.

LoLiGO PALLIDA Ycrrill, sp. nov. Plate XX, figs. 101, 101a. (p. 441.) 

 Body stout, tapering rapidly backward. Anterior border of mantle 

 with a prominent, obtusely rounded, median dorsal lobe, from which the 

 margin recedes on each side ; on the lower side the margin is concave 

 in the middle, with a projecting angle on each side. Caudal fin large, 

 about as broad as long, more than half as long as the body. Siphon 

 large and stout -, upper pair of arms considerably smaller and shorter 

 than the others, slender at tips, margined along the inner dorsal ridge 

 with a thin membrane. Second pair of arms stouter and longer, trique- 

 tral, slightly margined on the outer angle. Third pair much stouter and 

 considerably longer, with a membranous fold along the middle of the
