DISCUSSION OF SPECIES AND THEIK DISTRIBUTION. 1 .'{ 



The labia] fold extends a little way along the margins of the mouth. The distance 

 between the nostrils is rather more than one third of the length of the prseoral portion of 

 the snout. Teeth without serrature. The lower angle of the pectoral tin is producedinto 

 a tapering lobe. The lengtb «>i' the base of the second dorsal (without the spine) is one. 

 halt of that of the first (without the spine); and the lengtb oft lie base of the firsl (without 

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

 below the hind part of the seeond dorsal tin. Scales rather smooth, without median keel, 

 finely striated. Uniform brownish. (Oiinther.) 



This species has been found only off the coast of Portugal.

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

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

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

 rounded, not produced. Dorsal tins short, nearly equal in length: the length of the base 

 of the first (without the spine) is less than one-third of the distance between the two fins. 

 Extremity of the ventral below the end of the second dorsal. Scales pedunculate, with 

 lire in- six ribs each. Blackish brown, spotted with darker. 



Coast of Portugal; Madeira. Scarce. A fish of great depths and caughl in the same 

 way as the Espinheis. Not exceeding 35 inches in length. (Capello.) 



CENTROPHORUS SQUAMOSUS, Gmelin.

The labial fold extends a little way along the margin of the upper jaw, but not along 

 that of the lower. Teeth |§, the upper inclined outward, with a notch on the outer side 

 of the base, but not ou the inner: no median tooth in the lower jaw. The distance between 

 the nostrils is about one third of the length of the praeoral portion of the snout. Lower 

 angle of the pectoral tin very slightly produced. The length of the base of the second 

 dorsal fin (without the spine) is t wo t birds t hat of the lirst (without the spine): and the length 

 of the base of the first (without tin 1 spine) is about one-third of the distance between the 

 two fins. Extremity of the ventral fins below the middle of the second dorsal tin. The 

 xeales are leaf-shaped, with a strong median heel, quite free, inserted in the shin by a short stalk. 

 Brown. [GUnther.) 



('. squamosus also occurs only off the coast of Portugal.

Most closely allied to < '. squamosus. The labial fold extends a little w ay along the mar- 

 gin of the upper jaw, but not along that of the lower. Teeth 4,',, the upper small, straight, 

 triangular, with a coustricted cusp standing on a broad base: a median tooth in the lower 

 Jan-. The distance between the nostrils is a little less than one third of the length of the 

 prseoral portion of the snout. Lower angle of the pectoral fin very slightly produced: the 

 length of the base of the second dorsal tin (without the spine) is two thirds of that of the 

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

 one-half of the distance between the two tins; extremity of the ventral litis below the middle 

 of the second dor.-al fin. The Scales are leaf shaded, with a Strong median heel, quite free, in- 

 serted in the shin hi/ a short stalh; brown, with dark spots. [ < Hi ntlier.) 



The type of the species, a male, from Madeira, 43 inches long, was presented by J. V. 

 Johnson, Bsq. ; to tin- British .Museum.
