this, however, I feel justified in regarding as an error of 

 the draughtsman, for specimens received from the Naples 

 Zoological Station agree with Girard's description and 

 with Ball's specimen (compare fig. 3). 



(3) The horny ring of the large tentacular suckers is 

 not described by Jatta, but the figure {pi. 12, fig. 13, i^fi) 

 shows the teeth of the horny ring neither so acute nor so 

 widely separated as they appear to be in reality (see yf^. 5). 



The discrepancies above recorded are for the most 

 part explicable as due to state of preservation or difference 

 of age, and do not appear to be suitable for specific 

 distinction. I therefore conclude that all the specimens 

 of the genus Todaropsis are referable to one species, 

 which, in accordance with the rules of nomenclature, 

 should bear the name T. eblance (Ball). 



Subjoined is a table of the synonymy, with references
