 about twenty-four on each side. Maxillary rounded behind, not 

 dilated, extending to the mandibulary joint. Gill-rakers very short, 

 like tubercles ; there are about twelve on the lower branch of the 

 outer branchial arch. Origin of the dorsal fin midwaj- between the 

 root of the caudal and the occiput ; the anal fin commences below 

 the anterior third of the dorsal. Abdomen compressed, without 

 scutes. Pectoral fins scarcely reaching the ventrals. A broad, not
