The Irish Naturalist 



March, 



The edge of the mantle is nearly straight along the ventral 

 border, but unfortunately is damaged along the dorsal border, 

 and it is not possible to say if it is produced to a slight point 

 dorsally at B as figured by Steenstrup ('87). The caudal fins 

 are large, broad, and transversely rhomboidal, as described 

 and figured by Verrill ('80, '82). The suckers on the sessile 

 arms are strongly denticulated on the outer side of the rim, 

 with smaller or sometimes rudimentary teeth on the inner 

 side. The large suckers of the tentacular clubs are provided 

 with teeth similar to those described and figured by Goodrich 

 ('92), four of the teeth in each sucker being larger than the 

 rest. 



The arrangement of the smooth-rimmed suckers and tubercles 

 (connective apparatus) on the tentacular clubs agrees closely 

 with that figured by Steenstrup ('80, '87), and by Goodrich 

 ('92). The arrangement of the folds in the funnel groove, and 

 of the bridles, corresponds almost exactly with the description 

 and figure in Goodrich ('92) ; the eight folds within the velum 

 are very distinct, and there are four rudimentary folds on 

 either side without, but I do not find any trace of the two 

 outer apertures, and if present they must be very minute. 



On the inner surface ol the tentacular arms there are trans- 

 verse ridges (t.r.), commencing close to the last suckers of the 

 club and extending the greater part of its length ; there are 

 about fourteen of these ridges, the number observed by Good- 

 rich in the Salcombe specimen. 



Sthenoteuthis Bartrami, the other species of Stenoteuthis 

 referred to in Hoyle (1902), is smaller, the arrangement of the 

 suckers and tubercles of the connective apparatus is difierent, 

 and the tentacular arms are not much longer than the third 

 pair of sessile arms (Jatta, '96). 



There is in the Dublin Museum the club of the left tenta- 

 cular arm of a Squid that was captured at Killala, Co. Mayo, 

 many years ago. There are four tubercles on this tentacular 

 club, and only two on each of the tentacular clubs of the 

 Miltown Malbay specimen, but from the arrangement and 

 structure of the suckers I believe this Squid also to have been 

 a specimen of Sthenotetithis pteropus, of rather smaller dimen- 

 sions than the Miltown Malbay specimen.
