These specimens differ only in insignificant characters from the type in the 
“Challenger ” collection. The arms are proportionally a little shorter, but 
the general appearance, the form and disposition of the chromatophores, and 
the shape of the suckers are identical. There is no valve in the funnel, and as 
this character was recorded as doubtful in the case of the “ Challenger " specimen 
I have re-examined this latter with care, and. feel now convinced that the ap- 
pearance of a valve is due to the tip of the funnel organ (the pad alluded to in 
the “Challenger” Report, p. 107), having become separated from the wall of 
the funnel. 
The specimens were all immature, so that no sex indications were found in 
the viscera, but I conclude they are females because Verrill’s example of J. 
pygmaca, which was no larger than the smallest of them, already showed the 
enlarged. suckers on the third pair of arms which are believed to be character- 
istic of males. 
One of the specimens (No. 7960) shows the funnel organ very well (Plate 
5, Fig. 11). Tt consists mainly of two pads broader behind than in front, where 
they are prolonged into a kind of stalk and nearly meet, but are separated by 
the tip of a much smaller pad lying in the middle line and directed backwards. 
This median portion springs gradually from the dorsal wall of the funnel with- 
out any clear line of demarcation.
