Nine s])ecimens taken in tlie trawl at depths varying from 

 465-6G6 lath. All were examined without snecess for any

Family Enoploteuthidae. 



Genus OcxoroDOTEUTiiis, liiippell, 1884. 



Octopodoteuthis sicula, Riippell, 1884. 



A specimen taken in the trawl at 550-570 fath. This 

 individual agrees closely with Dr. Jaffa's description. The 

 tips of all the arms being mutilated, the sex cannot be 

 determined without injury to the specimen. This species 

 appears never to have been met with outside the Mediterranean 

 before, or of such a size. It measures 117 mm. across the 

 fins; from end of botly to mantle-margin 107 mm.; from 

 end of mantle-margin to bifurcation of first pair of arms 

 35 mm. 



The siphon projects 17 mm. above the mantle-margin. 

 No trace exists of the roots of the tentacles, which in this 

 species are moulted or re-absorbed in youth. 



Family Histioteuthidae. 

 Genus UiSTiOTEUTHis, Orbigny. 

 f listioteuthis bonelliaiia^ Fcrussac. 



Two specimens. One with a total length of 31 mm. was 

 taken in the triangle net at 70-80 fatli. from the surface over 

 soundings of about 800 fath. The other measures 12'J mm. 

 and was taken in the s[)rat-net on trawl at 775-795 fath. 

 The smaller specimen possesses no trace of web between the 

 arms, or of the black elongate swellings jn-esent in the larger 

 bjjceimen at the tips of all excejit the ventral arms. 



Not previously recorded from British-and-lrish waters.
