54 E. LÖNNBERG, ON THE CEPHALOPODS. 



The ink-sac is however situated further back in the pallial 

 cavity and its posterior end lies rather close to the base of 

 the lef't gill. The funnel-organ is largely developed and 

 resembles that of the Ommatostrephini (f. inst. Todarodes). 

 The median portions are anteriorly confluent but diverge poste- 

 riorly and extend on the snrfaces of the muscnli retractores in- 

 fundibuli. The length of this median portion is in the larger 

 specimen 19 mm. The lateral pads are well defined, as well from 

 each other as from the median portion; their dimensions in the 

 larger specimen are 15 mm. in length by 5 in breadth. Thegladius 

 of the smaller specimen (althongh it was broken no piece was da- 

 maged) measnred abont 92 mm. in length by 8 in breadth in the 

 widest place. The width is thus nearly 9 % of the length 

 (bnt only 6 % in Gonatus fabricii). The anterior third of the 

 gladins is only 3 mm. broad with brown lateral thickenings. 

 At the end of the anterior third the gladins becomes late- 

 rally expanded and has its greatest width abont the middle 

 where also the edges are strengthened by marginal thickenings 

 At the same time the above mentioned thickenings from 

 the narrow anterior part become more and more con- 

 vergent and nnite into one median. At the posterior end 

 the second marginal thickenings eonverge and leave the edge 

 where new ones of a similar kind replace them. The gladins 

 is here at the posterior end strongly concave, and at last the 

 margins meet to form the »hollow cone». But the posterior 

 end of that is curved ventral] y and seems to be solid. This 

 corresponds to the part of the gladins in G. fabricii which is 

 described by Hoyle (1. c. p. 123) as consisting »of cartiiage bnt of 

 a degenerate type >. This solid portion of the cone is abont 2 mm. 

 Gonatus fabricii Licht, is known to be distributed over 

 the arctic Atlantic from Greenland, where it is common, and 

 Iceland to the Porsangerfjord in Norway, but it probably 

 inhabits the whole arctic ocean as it has been found at 

 Kamtshatka and also at Japan. How far south it goes in 

 the Pacific and in the Atlantic is not sufnciently known as 

 yet. The Zoological State-Museum in Stockholm has however 

 a large specimen from the Mediterranean, and a specimen 

 is taken from the stomach of a fish 100 miles south of 

 Newport R. I. (Verrill). In the Challenger Report on 

 the Cephalopods Hoyle quotes Steenstrup for two localities 

 for »Gonatus fabricii» namely: »South of Cape of Good
