4:6 Description of a New Generic Form of 



few of the Gohies^ or at least, of those inhabiting the seas of 

 China and Japan, and of the East Indies, appear to have this 

 plan of squamation. In most of the species of those seas, 

 although there are ctenoid scales on the sides, the scales of the 

 anterior portion of the back and of the nape and head, when 

 any are present, have a true cycloid structure with a more or 

 less eccentric nucleus. Of all the species collected by the 

 North Pacific Expedition, fitted out by the Federal government, 

 but a single species has the same mode of squamation as the 

 one now described ; it is a species which appears to have been 

 named Gohius platycephalus by Sir John Richardson,* and 

 was obtained at Hong Kong, China, by Mr. Stimpson, the na- 

 turalist of the Expedition. To that species, the present writer 

 has given the generic name of Glossogohius. There is little 

 necessity of a comparison of the present genus with that one, 

 for the similar structures of the scales on the back is the only 

 generic character they have in common Glossogohius has a 

 depressed head, protruding lower jaw, an anteriorly free and 

 deeply emarginated tongue, and several rows of stout teeth in 

 each jaw, the outer of which are hooked backwards. Eucteno- 

 gobius is also well distinguished by its single row of teeth in the 

 Tipper jaw ; in this it differs from all the described forms ; but 

 a species obtained during the cruise of the North Pacific Expe- 

 dition has the same peculiarity ; it is, however, very distinct in 

 other respects from the present, and will be hereafter described 

 as the type of a new genus to which the name of Synechogohius 

 has been given. The relations between that genus and Eucte- 

 nogobiios, are more intimate than with any others of the tribe, 

 but Synechogohius is especially distinguished by the cycloid 

 scales of the anterior portion of the back, the'papillated tongue 

 with parallel sides, and the larger teeth which are also on the 

 margin of the jaw and not covered by the lips ; the lower jaw 

 also projects beyond the upper, and the caudal fin appears to
