 gobioideK, Cuvier & Valeucieuues). 



iSnlijoit, Ogilby, Proc. Liim. Soc. N.S. Wales, xxi., 1897, p. 7-40 (Eleotris 

 CDxii, Krefft). 



Body subcyliudrical aiiterioily, compressed posteriorly ; caudal 

 peduncle about half as long as broad. Scales of moderate size, mostly 

 ctenoid but becoming cycloid anteriorly and on the abdomen ; they extend 

 forward to between the posterior orbital margins. Head about as broad 

 as deep, snout obtusely conical ; mandible projecting. Operculum covered 

 with small scales ; cheeks with somewhat rudimentary scales which are 

 most plentiful on the postorbital portions. Lines of minute mneigerous 

 papillfB extend across the cheeks and opercles, around the preopercular 

 margin, and from each side of the snout to above the eye. A broad band 

 of villiform teeth in each jaw; no enlarged outer row. Tongue free and 

 rounded anteriorly. Gill-openings extending foi'Avard below, separated 

 by a rather broad isthmus; exposed edge of the shoulder-girdle forming a 

 smooth ridge, with a pit at its lower angle. Pseudobranchia? present ; 

 gill-rakers short and thick, about nine on the lower limb of the first arch. 

 First dorsal iHJunded, with six to seven spines ; second doisal short, 

 with nine to eleven rays. Pectoi*al and caudal I'ounded. Ventrals i/5, 

 completely separated. 



Si/iioin/t)iii. — A comparison of the genotypes (»'. ijobioidef and M. roxii 

 shows that they are similar in all the above characters. Waite-'^ has 

 united Miilyvd with Kreffiiiii, but it is distinguished from that genus in 

 having the interorbital space naked instead of scaly. 



Jordan and Evermann-^ have united their genus (jNiftqiiillfnt with 

 (^dbiniinirpliKt^, but it differs in the chai-acter of its dentition. It has an 

 enlarged outer row of teeth in each jaw, and there is a snbcaniniform 

 tooth on each side of the mandible ; in Gohiuiiiurfhus the teeth are subeqnal 

 in size.
