A. M Verrill — North American Cephalopods. 411 



Brown's Bank, olf Nova Scotia, taken from the storaacli of a cod 

 (lot 950). Presented to the U. S. Fish Commission by Capt. Wm. 

 Denipsy and crew, of the schooner " Clara F. Friend," June, 1881. 



The internal anatomy is somewhat peculiar in several respects, but 

 will not be fully described in this place. 



The gills are short and broad, with very long lamella?. The re- 

 productive organs occupy a large part of the visceral cavity. The 

 testicle is a large, thick, broad-ovate organ, with the two sides folded 

 together around and closely united to the large coecal lobe of the 

 stomach. The testicle does not extend back beyond the origin of the 

 caudal fin, the visceral cavity being very narrow in that region. 

 The prostate gland and vesiculse seminales are large and swollen, and 

 the spermatophore-sac is also large. The efferent duct is large and 

 long, extending far forward ; it expands at the end into a spade-like 

 form, with an acute tip ; its orifice is oblique ear-sh.-iped, situated on 

 one side, near the end, and is protected by a lobe or flap. The stom- 

 ach is saccular and the large coecal lobe is not very long. The liver 

 is thick. The posterior aorta goes far back, nearly to the origin of 

 the fin, before dividing, for the median septum of the branchial cavity 

 is placed far back. The ink-sac has the ordinary pyriforra shape. 



A smaller, female specimen, probably belonging to this species, was 

 taken by Captain Z. L. Tanner, on the "Fish Hawk," October 10, off 

 Delaware Bay, in 435 fathoms, station 1048. 



This specimen agrees nearly with the type specimen, described 

 above, in the form and proportions of the body, head, arms, caudal 

 fin, pen, etc., and in the structure and denticulation of the suckers. 

 The caudal fin is slightly broader in proportion, while the suckers are 

 deeper and relatively smaller, especially those on the ventral arms, 

 which are decidedly smaller than those on the lateral ones. They 

 are finely and sharply denticulated on the outer edge, as in the type. 



The color is, however, quite different, for in this example the skin 

 and flesh are translucent and beaiitifully specked with regular, round, 

 often rather large, not crowded, dark brownish red chromato- 

 phores ; the larger of these, especially on the under side of the fin 

 and body, are ocellated ; on the head and arms the chromatophores 

 become smaller and more crowded, more nearly as in the type. The 

 row of large dark purple spots, along the ventral ai'ms, are, in this 

 example, decidedly raised and wart-like. One of the tentacular arms 

 is perfect. These are very long and slender, and bear, along their 

 whole length, relatively large, rounded, wart-like, dark purple, sessile 

 suckers, having a small central pit. These suckers are about two-
