Except that it is a little smaller, this specimen exactly resem- 
bles the illustration of Jatta (/.c., tav. 4, fig. 2) having the same 
long narrow body, prominent eyes, and pale greenish-yellow 
colouring with delicate slightly-defined dark reticulations. The 
fourth arms are much the longest and thickest, being six or seven 
times the length of the mantle, while the dorsal pair is only about 
three times of this length. None of the suckers is specially en- 
larged. Umbrella attaining about one-eighth of the length of the 
arms, widest ventrally, and extending prominently on the upper 
part of arms forming large crests. The mantle opens a little below 
and at the ventral edge of eye. Funnel small andextending about 
half way to the margin of umbrella. Two ocular cirri are present 
over each eye and a few tubercles are scattered on the dorsal sur- 
face of the head and mantle. Ventral surface smooth except for 
a faintly-indicated median groove. The striated sperm canal and 
small terminal organ of the hectocotylized arm agree with Jatta’s 
description. A Bay of Naples specimen, purchased from the 
Zoological Station of Naples by the Dublin Museum, has the typi- 
cal round body represented by Verany, and by Jatta on pl. 24, 
figs. 10, 12. Jatta mentions that this is due to the mantle of 
specimens in alcohol becoming contracted, and, therefore, swollen 
in the middle, restricted at each end, and furnished with a median 
ventral groove. He describes the surface as being perfectly smooth
