IX. Notes on the Type Specimen of Loligo eblanae, 



Ball.

Thanks to the courtesy of my friend Dr. R. F. Scharfif, 

 of the Science and Art Museum, Dublin, I have recently 

 had an opportunity of examining the cephalopod de- 

 scribed so long ago as 1841 by the Irish naturalist, 

 Robert Ball, under the name of Loligo eblance. As the 

 result of the investigation has been to confirm an opinion 

 which had been formed by others as well as myself, that 

 this was not distinguishable from another species de- 

 scribed by Girard under the name of Todaropsis veranyi, 

 I have thought it worth while to set down the facts upon 

 which this view is based. 



The distinctive characters on which the genus Todar- 

 opsis is based are as follow : — 



Funnel groove smooth ; tentacles without connective 

 apparatus ; horny rings of the large tentacular suckers 

 with numerous subequal short acute teeth ; the terminal 

 suckers of the tentacle in four rows ; lateral arms without 

 a membranous expansion. 



The genus has been accepted as valid by Jatta, 

 Posselt, Nichols, and Pfeffer, and the only doubtful point 

 is whether it contains two species or only one. 



In the first place it seems desirable to give a 

 description of the specimen as full as its state of preserva- 

 tion permits, accompanied by figures of some of the more 

 critical parts. 



The Body {fig. i) is bluntly fusiform, its greatest
