REPORT ON THE CEPHALOPODA. 159 



It is clearly distinguislied. from that species, however, by the following characters :^ 

 (1) the length of the arms, which are about half the length of the body and not one- 

 fifth, (2) the size of the tentacular suckers, which are much larger than those of the sessile 

 arms, (3) the form of the gladius (compare fig. 15 with Keferstein's drawing),^ and (4) 

 the denticulation of the horny rings of the suckers.^

Habitat. — Station 203, off Panay, Philippine Islands, October 31, 1874; lat. 11° 6' 

 N., long. 123° 9' E. ; 20 fathoms ; mud. Two immature specimens. 



The Body is about four times as long as broad, cylindrical anteriorly, and pointed 

 behind. The Jin is rather less than half the length of the body, about as long as broad, 

 and with rounded lateral angles. The mantle-margin curves out rapidly to a triangular 

 process in the dorsal median line, for the rest it is almost transverse, except where it 

 forms two obtuse angled processes, one at either side of the ventral emargination, 

 which receives the siphon. 



The Head is comparatively broad and with rather prominent rounded eyes. The 

 siphon is moderately large and of the usual form. 



The Arms are unequal, the order of length being 3, 2, 4, 1, and about half as long 

 as the body. The dorsal have a distinct keel on the upper margin, the second are keeled 

 on the ventro-lateral aspect, the third are stout and flattened and have a broad web on 

 the outer aspect, which unites with the web running up the dorso-lateral aspect of the 

 ventral arms. The suchers (fig. 2) are in two series throughout, with short peduncles, 

 and not very oblique; their horny rings bear nearly twenty distant blunt teeth (figs. 3, 4). 

 The left ventral arm is heetocotylised for about two-thirds of its length (fig. 5) ; there 

 being as usual two rows of conical papiUse. The papillae of the dorsal series are 

 decidedly smaller than the others and bear each a minute sucker at the tip (fig. 6). 

 Those of the ventral series are stouter and not so evenly conical as the others, tapering 

 more rapidly towards their tips ; they bear also a somewhat elevated oval patch on one 

 or both their sides, and a few of the proximal ones have each a small sucker at the tip 

 (figs. 7, 8). At the base of the arm, lying transversely across it is an oval raised 

 cushion with a rough papillate surface (fig. 5). The umhrella is absent. The buccal 

 membrane has the usual seven points, each of which bears a few suckers. The outer lip 

 is thin, the inner thin and paj)illate.
