528 ORDER MALACOPTERYGII APODES. 



M. Christini, Risso. Altogether covered with small 

 lines or small points, brown and crowded, which make 

 it appear of a uniform brown *. 



There are some with round lateral teeth on a single 

 range ; the vomerian, equally round, are on two 

 ranges ; the anterior are conical 2 . 



We have some with round lateral teeth on two 

 ranges, with vomerian teeth equally round on four 

 ranges, forming a sort of pavement. This species has 

 scarcely any apparent fins 3 . 



Some, in fine, are known with pectiniform teeth on 

 several ranges, and the Mediterranean yields one of 

 this sort, 



M. saga, Risso, 1st edit. f. 39. Remarkable for 

 its elongated jaws, round and pointed, and its tail 

 elongated into a very sharp point 4 . . 



Sphagebranchus, Bl., 



Differ from the muraenae principally by the apertures 

 of their gills being approximated one to the other 



1 The other species are new. 



2 Murenophis etoile, Lacep., or M. nebulosa, Thun. Seb. II. lxix. 

 1.; M. ondule, Lacep. V. xix.. 2. (M. catenatus, BL, Schn.) ; M. 

 sordida, Cuv., Seb. II. lxix. 4. 



3 Gymnomurene cerclee, Lacep. V. xix. 4., or Murcena zebra, 

 Shaw, Seb. II. lxx. 3. 



4 The Nettasoma melanura, Rafin. Caratt. pi. xvi. f. 1., is at 

 least very much approximated to this Murcenophis saga of 

 Risso. 



N.B. The Dalopkis, Rafin. Caratt. pi. vii. f. 2. and 3., should be 

 muraenae without teeth, but we are not acquainted with them.
