 Snout blunt ; nostrils extending to the mouth, with a short valve at 

 the internal margin, from which proceeds a long cirrus extending to the 

 mouth ; a second short valve at the external margin of the nostrils ; 

 mouth convex ; the folds of the angle of the mouth divided by a deep 

 fissure in an upper and lower fold ; the internal extremity of the lower 

 fold separated from the skin of the under lip by a more or less deep, 

 vertical furrow ; teeth very numerous, upwards of ten close series, their 

 base rhomboidal, with a central conical apex, with two to four gradually 

 decreasing blunt points on each side ; the fifth branchial opening 

 almost hidden in the fourth ; both situated above the pectoral fins ; 

 spiracles very minute, immediately behind the eyes ; anterior dorsal fin 

 opposite the ventrals ; posterior dorsal partly in front of, partly opposite 

 the commencement of the anal ; the latter fin nearer the caudal than 

 the ventrals, yet not immediately in front of the caudal ; the latter 

 with a trace of an inferior lobe ; pectoral fins longer than in the rest of 

 Scyllioidce.

The anterior dorsal fin commences a little behind the origin of the 

 ventrals, but extends farther back than the termination of the latter. 

 The posterior dorsal commences a little in front of the anal and termi- 

 nates a little in front of the termination of the latter fin. The scales 

 are broad lanceolate or sub-rhombic with an indistinct central tubercle. 

 The denticulations of the posterior margins are very indistinct, and the 

 scales which are worn down have a polished granular appearance. In 

 the upper jaw appear but three, in the lower four series of teeth, the
