This is the first of the two species indicated by me in the former 

 part of this List or Synopsis. Of the second sort, there mentioned 

 as having been seen by Miss Young, and which I have there doubt- 

 fully referred to E. naucrates, L., no fresh example has occurred. 

 I should now be much inclined to consider it identical with E. vit- 

 tata ; but Miss Young affirms that it was " certainly plain-coloured."

A single individual only has occurred, precisely answering to the 

 description above referred to. It measured eleven inches in length. 

 I could not detect the slightest rudiment of pectoral fins.

A most elegantly- coloured little species, which I cannot refer with 

 certainty to any already described. Only two individuals have hi- 

 therto occurred. The first was little more than two inches long : 

 the second nearly twice as large. 



The Orthagoriscus of Madeira, called by the fishermen, " Peixe 

 Porco," or " Bouto," I forbear at present to designate further, not 

 having seen a sufficient number of individuals to determine its cha- 

 racters. The caudal fin is produced into a short point in the mid- 

 dle, not truncate, as in all the figures to which I have access of the 

 European Sun-fishes.

An Squalus ustus, Dum. 



It is perhaps only for want of better materials for comparison that 

 I have been unable to refer this Shark precisely to the above-indi- 

 cated or to some other described species. It is about three feet long.
