REPORT OF COMMISSIONER OF FISH AND FISHERIES. [212] 
The gills are short and broad, with very long lamellz. The repro- 
ductive 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 cecal 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 vesicula seminalis are large and swollen, and the spermatophore-sac 
is also large. The efferent duct is large and long, extending far for- 
ward; it expands at the end into a spade-like form, with an acute tip; 
its orifice is oblique ear-shaped, situated on one side, near the end, and 
is protected by a lobe or flap. The stomach is saccular, and the large 
cecal 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 pyriform shape. , 
A second smaller specimen, which proves to be a young female, in ex- 
cellent preservation, was trawled by Lieut. Z. L. Tanner, on the “Fish 
Hawk,” October 10, 1881. This was taken, 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 de- 
cidedly 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 beautifully specked with regular, round, 
often rather large, not crowded, dark brownish red chromatophores; 
the larger of these, especially on the under side of the fin and body, are 
ocellated; on the head and arms the chromatophores become smalier 
and more crowded, more nearly as in the type. The row of large dark 
purple spots, along the ventral arms, 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, rela- 
tively large rounded, wart-like, dark purple, sessile suckers having a 
small central pit. These suckers are about two-thids as broad as the 
diameter of the arm, and from close to the base of the arm to the dis- 
tal fourth they are separated by spaces mostly equal to about twice 
their diameter; distally they are less numerous. The tentacular club* 
*This arm differs considerably from the one described on p. [119] and figured on 
Plate XXXII, figs. 1-1), especially in having much more numerous sessile suckers 
along the whole length of the arm, and in having sharply denticulated suckers on the 
club. This may indicate that the latter belonged to a different species. But it is 
possible that the latter had suffered injury, before preservation, sufficient to cause 
these differences.
