of affinity, the very tishermen regarding it as some kind of " Dourado" 

 {CoryphcBna), which it resembles, both in general aspect and in the 

 form of the head and profile. Something about the mouth and pro- 

 file reminds one also of the turbot, whilst in the shape of the body, 

 and perhaps of the dorsal and the anal fins, it resembles the " En- 

 xareo" {Caranx luna, Geoffr.). The colour of the fins recalls to mind 

 the Lampris. 



The length of this example was five-eighths of an inch less than 

 three feet.

Two examples of this very handsome and most distinct new spe- 

 cies of Dory have occurred. There is no danger of confounding it 

 with any other of the genus yet recorded, for the Z. Childrenii of 

 Bowdich, so obscurely indicated in the ' Excursions in Madeira,' was 

 most probably the Boar-fish {Capros Aper, Lac). 



Sternoptyx diaphana (Herm.), Cuv. K. An. ii. 316. t. xiii. f. 1. 



The acquisition lately of an example of this most rare and curious 

 of fishes has confirmed a suspicion I have long entertained, that the 

 true position of its genus is near Zeus, It has also some relation to 

 Trachichthys, but I think only in the way of analogy. 



This little fish was taken in August at sea, between Madeira and 

 St. Mary's, the southernmost of the Azores, about eighty miles to 

 the south-east of the latter island, in a calm smooth sea. It is not 

 a little remarkable, that after so long an interval, Sternoptyx dia- 

 phana, originally discovered by Hermann so long ago as 1774, in 

 the West India islands, should have been rediscovered thus near 

 the Azores ; that is, in the locality in which the cognate St. Olfersii, 

 Cuv. /. c. t. xiii. f. 2, has yet alone been found.
