Mr W. E. Hoyle on Loligopsis and some other Genera. 319 



The phrase " Longueur totale, plus d'un metre," refers to 

 the Madeira specimen, while, curiously enough, the remainder 

 of the dimensions are taken from that of Lesueur. 



The general form of the body is the same in both, the 

 tentacles are absent in both cases, but in Lesueur's the stems 

 remain, while in the larger individual they have been cut 

 off close to the roots. 



Of the figures, PL vi., Figs. 1, 2, 3, are copied from Lesueur's 

 oridnals. PL iv., Figs. 1-6, mioht have been taken from either, 

 while Figs. 7, 8, were certainly taken from the Madeira 

 specimen, for the typical Loligo pavo has no sharply-toothed 

 suckers, but those even at the extremity of the arm are 

 provided with blunt teeth, though they are not so square-cut 

 as those of the basal suckers. 



The gladius (PL vi.. Fig. 4) was probably drawn from the 

 Madeira specimen, from which it has been removed, though 

 incompletely, the posterior tip remaining in the animal. 



One expression used by de Eochebrune in speaking of 

 Lesueur's specimen is unfortunate, — he says of the arms 

 (loc. cit, p. 5) : "1 serie cotyledonorum armatis," while 

 d'Orbigny, in his generic diagnosis and in his figure, gives 

 two rows. In point of fact, the two expressions are almost 

 equally correct ; there are either two rows of suckers not far 

 removed, or one row arranged in a zig-zag manner which in 

 certain positions appears like one straight row. 



I have already given reasons for thinking that Desmoteitthis 

 is synonymous with Taonms. I shall now adduce a few 

 arguments which lead me to believe that the specimen which 

 Verrill obtained from the northern edge of the Gulf Stream, 

 and which he believed to be identical with Taonms hyper- 

 horenSy w^as none other than Taonius pavo. 



That it differs from the former of these may be seen by a 

 most cursory examination of the type specimen, or of the 

 drawing to be published in the report on the " Challenger " 

 Cephalopoda, and as may be also seen by a careful comparison 

 of Verrill's figures with Steenstrup's description.^ Taonius 

 hyperhoreus is there defined by its differences from T. pavo, 

 viz. : " (1.) the length and breadth of the fin, which is half 

 ' Overblik, p. 84 (16).
