DISCUSSION OF SPECIES AND THEIR DISTRIIiUTION. 13 



The labial fold extends a little way aloiiy- the margins of the mouth. Tlie distance 

 between the nostrils is rather more than one-third of the length of tlie |ineor;d ])ortion of 

 the snout. Teeth without serratnre. The lower angle of the iieetoral lin is ])rodueed into 

 a tapering lobe. The lengtii of tlie base of the second dorsal (without the spine) is one 

 half of that of the first (without the s|)ine); and the length of the base of the first (without 

 the spine) is one half of the distance between the two fins. Extremity ot the ventral tins 

 below the hind part of the second dorsal tin. ,Sc(ilcs rather smooth, icithont mcituin led, 

 Jiiiety sfriatcfJ. Uniform brownish. (Gihithcr.) 



This species has been found onlj' off the coast of rortugal.

Labial groDve prolonged forward, nearly meeting in the median line of the snout. 

 Upper teeth very small, narrow lanceolate. The distance between the nostrils is about two 

 fifths of the length of the praioral portion of the snout. Lower angle of the pectoral 

 rounded, not produced. Dorsal fins short, nearly equal in length; the length of the base 

 of the first (without the sjnne) is less than one-third of the distance; between the two tins. 

 Extremity of the ventral below the end of the second dorsal. Scalt's j)eih(iiciil<ifi\ irith 

 five or six ribs each. Blackish brown, spotted with darker. 



Coast of Portugal; Madeira. Scarce. A fish of gi-eat dci)ths and caiiglit in the same 

 way as the Espinheis. Kot exceeding 3~> inches in length. (C((peIlo.)

The labial fold extends a little way along the mai.giu of the upper Jaw, but not along 

 that of the lower. Teeth ;-7j, the upper inclined outwai-d, with a notcli on the outci' side 

 of the base, but not on the inner; nn median tooth in the loirer jaic. The distance between 

 the nostrils is about one-third of the length of the pra'oral portion of the snout. Lower 

 angle of the pectoral fin very sligiitly produced. The length of tlie base of the second 

 dorsal fin (without the spine) is two-thirds that of the first (without tlie spine); and tin; lengtii 

 of the base of the first (without the spine) is about one-third of tiie distaiii-c between the 

 two fins. Extrenuty of the ventral fins below t\n' middle of tlic second dors:il lin. The 

 scales are leaf-shaped, irith a stromj median keel, quite free, inserted in. the slin hi/ a short stall:. 

 Brown. (Giinther.)

Most closely allied to (!. sqnanwsns. The labial fold extends a little way along tln^ mar- 

 gin of the upper .jaw, but not ah)ng that of the lower. Teeth 4;,, the upper small, straight, 

 triangular, with a- constricted cusp standin.g on a broad base; a median tooth in the lower 

 jaw. The distance between the nostrils is a little less than one tliird of the lengtii of the 

 pneoral portion of the snout. Lower angle of the pectoral fin very slightly produced; the 

 length of the base of the second dorsal fin (without tiie spine) is two-thirds of that of the 

 first (without the spine), and the length of the base of the' first (without the spine) is nearly 

 one half of tlif distance between the two fins; extremity of the ventral fins below the middle 

 of the second d(»isal tin. The scales are leaf-shaped, with a stronr/ median heel, quite/ree, in- 

 serted in the shin by a short stall;; brown, with dark spots, ((iilnther.) 



The type of the siiecies, a male, from Madeira, 43 inches long, was pieseiitcil by .1. V. 

 Johnson, Esq., to the British IMiiseiun.
