Olivaceous; back with four distinct brown spots, tlie longest nearly 

 twice as long as eye, and extending a little below lateral line, there, 

 blending with a wavy hiteral stripe; dorsals and pectorals with inter- 

 rupted black bands; lower fins plain whitish. Body elongate. A small 

 tubercle above each eye; four preopercular spines, the longest about 

 as long as eye, and with two or three processes. Space between eyes 

 deeply concave, completely covered with bony granulations, as are the 

 crown and neck; similar granulations on hinder margin of orbit, on 

 suborbital stay and on o])ercles. Skin of bodj^ naked. Pectorals, and 

 in males the ventrals also, reaching beyond vent; maxillary reaching 

 to below eye. Head 3j| (including caudal); dej)th 7^. D. XI-IG; A.

 (Ptijonotus Gthr. ) 

 (Girard, Proc. Bost. Soc. Nat. Hist, iv, 18, 1851: type Triglopsis thompsoni Grd.) 



Body and head slender. Skin naked; lateral line chain-like. Teeth 

 on vomer, none on the palatines. Eyes large, the interorbital area con- 

 cave; bones of lower part of head extensively cavernous; a small but 

 distinct slit behiud last gill ; gill-membranes almost free from the 

 isthmus, forming a broad fold across it; preopercular spines straight, 

 simple; fius large. Freshwater fishes, closely related to Coitus, to 

 which genus the single known species should, perhaps, be referred. 

 Its relations with the group called Oncocottus are certainly intimate.
