DISCUSSION OF SPECIES AND THEIR DISTRIBUTION. 13 



The labial fold extends a little way along the margins of the month. The distance 

 between the nostrils is rather more than one third of the length of the pneoral jiortion of 

 the snont. Teeth without serrature. The lower .ingle of tlie pectoral finis prodneed into 

 a tapering lobe. The length of the base of the second dorsal (withont the spine) is one- 

 half of that of the first (withont the spine); and the length of the base of the first (withont 

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

 below the hind part of the second dorsal fin. Scuh.s rutlur smooth, ivithout ineiliaii l;cd, 

 finvly .striated. Uniform brownish. (Giinthcr.) 



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

Labial groove 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- 

 flftlis of the length of the pr<i3oral portion of the snout. Lower angle of the pectoral 

 rounded, not i^roduced. Dorsal fins 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 dcnsal. Scales pednnvntatv, with 

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



Coast of rortugal; Madeira. Scarce. A fisli of great depths and caught in the same 

 way as the Espinheis. JS^ot exceeding 35 inches in length. (Capcllo.)

The labial fold extends a little way along the margin of the upper jaw, l)ut not along 

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

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

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

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

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

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

 two fins. Extremity of the ventral fins beh)w the middle of the second dorsal fin. The 

 scales arc leaf-shiipcd, with a strony median keel, (ptitc free, inserted in the skin hy a short stalk.

C. s(ji((imosHs al.so occurs only off the coast of Portugal. 



CENTKOPHORUS DUMEKILII,(.)(iiixson). 

 Alachtphiliis DumeriJii, Jmissoy, Proc. Zool. Soc, 1867, p. 713. 



Most closely allied to ('. siiuamosus. The labial fold extends a little way along the mar- 

 gin of the upper jaw, but not along that of the lower. Teeth |^, the upper small, straight, 

 triangular, with a constricted cusp standing on a broad base; a median tooth in the lou-cr 

 jaw. The distance between the nostrils is a little less than one-third ot the lengtli of the 

 Ijrffioral portion of the snout. Lower angle of the jiectoral fin very slightly produced ; the 

 length of the base of the second dorsal fin (without the 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 the distance between the two fins; extremity of the ventral fins below the mi(Ulle 

 of the second dorsal fin. The scales arc leaf-shaped, with a strong median keel, qnitefrcc, in- 

 serted in the skin by a short stalk; brown, with dark spots, ((iiinther.) 



The type of the species, a male, from Madeira, -13 inches long, was presented b.\-.I. \'.
