anterior end, gradually narrowing to the very narrow slender portion, 

 about three inches from the posterior end, beyond which there is a thin 

 margin, which expands into a lanceolate form, widest at 1.25 inches from 

 the end; the terminal portion forms a short, hollow hood, formed by the 

 infolding of the margin, and marked by slender, divergent, raised lines, 

 stronger laterally, and with a dorsal keel. The central rib begins at the 

 anterior end, increases in size to the middle region, then narrows to the 

 slender part, where it forms a slender, prominent rib, only visible dor- 

 sally, and then becoming confluent with the lateral ribs extends as a 

 sharp keel to the end. The lateral ribs commence at about .75 inch 

 from the anterior end, and each at first consists of three riblets; farther 

 back another appears ou the outside margin, but is separated only by 

 a slender groove, and toward the slender part of the pen they all co- 

 alesce into a single rib on each side, which nearly meet in the middle line 

 ventrally, where they are separated by a slender groove, which disap- 

 pears farther on. Total length of pen, 349 mra (13.75 inches); greatest 

 breadth, 22.5 mm (.90 inch); length of posterior cone or hood, .9 mm (.35 

 inch); breadth of posterior expansion, 15""". 



This specimen is entire, except that it has lost the clubs of the ten- 

 tacular arms. It is in fair condition, though considerably contracted 

 by long preservation in too strong alcohol. The head, however, has 

 been pulled out from the mantle to an unnatural extent, so as to increase 

 the total length from 3 cm to 4 cm at least. The ventral arms do not show 

 any of the sexual modifications characteristic of the male squids, there- 

 fore, it is doubtless a female. 



Most of the measurements are given in the table with those of S. 

 megaptera (p. 103); some of the more general are as follows: Length 

 from end of body to tip of dorsal arms, 69.8 cra (27.5 inches); to edge of 

 mantle, dorsally, 37.5 cm (14.75 inches); to base of dorsal arms, 52 cm (20.5 

 inches); to center of eye, 47 cm ; to lateral insertions of fin, length, 17 cm 

 (6.75 inches) ; to outer angle of fin, along posterior edge, 18.4 cm (7.25 

 inches) ; breadth of fins transversely, 28.5 cm (11.25 inches) ; outer angle 

 to lateral insertion, along front edge, 14 cm (5.5 inches); between lateral 

 insertions, 5 cm (2 inches); breadth of body, 11.9 cm ; circumference of 

 body, 29.2 cm (11.5 inches). 



This specimen, which was obtained at Bermuda, by Mr. G. Brown 

 Goode, now belongs to the museum of Wesleyan University, Middletown, 

 Conn. Mr. Goode informs me that it was picked up on the north shore 

 of the island, in December, 1876, and that it was regarded by the inhab- 

 itants as a novelty or great rarity, and was noticed as such in the local 

 newspapers. 



Stenotcuthis pteropus has been recorded from the Mediterranean Sea 

 and the warmer parts of the Atlantic Ocean.
