PLATESSA.] PISCES (OSSEI) MALACOPT. 459 



breadth of the body: mouth very small; lower jaw longest; commissure 

 of the lips, when the mouth is closed, nearly vertical : teeth cutting, set 

 closely together, with even summits, extending the whole length of the 

 jaws : eyes on the right side, large, placed obliquely, the lower one being 

 more advanced than the upper, close together, with an osseous ridge 

 between; diameter of the orbit equalling one-third the length of the 

 head : lateral line almost perfectly straight throughout its whole course, 

 but not exactly parallel to the axis of the body, inclining slightly upwards 

 anteriorly; half-way, its course is found to be a very little above the 

 mesial line: skin smooth above and below: scales large: dorsal fin 

 commencing above the eye, at a distance from the end of the snout 

 equalling nearly half the length of the head; rays short at first, but 

 doubling their length beyond the line of the pectorals ; from that point 

 nearly even throughout ; greatest elevation of the fin contained five times 

 and a half in the breadth of the body : anal commencing just opposite the 

 point at which the dorsal rays begin to lengthen, answering to that fin, 

 and terminating in the same line, a little before the caudal : caudal rounded 

 at the extremity ; its length equalling half the breadth of the body : pec- 

 torals attached just behind the posterior angle of the opercle, their length 

 about half that of the head : ventrals immediately beneath them, of the 

 same length.

{Colour of a specimen in spirits.) Yellowish brown. 



The above description of this species, which is a recently acquired ad- 

 dition to the British Fauna, was taken from a specimen in the Museum 

 of the Zoological Society, procured in the London market, in May, 1833. 

 Mr. Yarrell has another from the Frith of Forth, sent him by Mr. R. H. 

 Parnell, by whom it appears to have been considered as an undescribed 

 species f . This last gentleman states that it is known to the fishermen 

 in that neighbourhood under the appellation of Craig fluke. I have 

 ventured to suggest the English name of Pole, as being in unison with 

 the Latin name which it has received from Cuvier. 



146. P. Limandoides, Nob. (Sandnecker.) Oblong- 

 oval : both eyes equally advanced towards the mouth :

LENGTH. From ten to twelve inches. 



DESCRIPT. (Form.) Oblong-oval ; the body more elongated than in the 

 last species : greatest breadth, dorsal and anal fins excluded, about one-third 

 of the entire length ; head rather more than half the breadth : mouth con- 

 siderably larger than in the P. Pola ; lower jaw longest, ascending obliquely 

 to meet the upper ; teeth conical, sharp-pointed, a little distant from each 

 other: eyes on the right side, and both equally advanced towards the 

 mouth ; between them an osseous ridge, produced behind, and falling in 

 with the commencement of the lateral line ; diameter of the orbit one- 

 fourth the length of the head : lateral line straight throughout its course : 



* The numbers of rays in the dorsal and anal fins are taken from Mr. Parnell.
