I. Uranoscopus (Linn.) Gill. 



Trochinus sp. Artedi, Genera Piscium. 



Uranoscopus Linn., Systema Natune. 



Callionymus sp. Gronovius. 



Head above completely covered with the bony armor. Preoperculum armed 

 beneath with four to six spines. Lower jaw with its inferior margin entire 

 and not abruptly notched ; its internal membranous velum provided with a 

 filament. Body covered with scales. Two dorsal fins ; the first with three, four 

 or five short spines. The second corresponding to the anal. 



The genus Uranoscopus is now restricted to those species which resemble 

 the long known Uranoscopus scaler in the form of body, squamation, fins, ar- 

 mature of the head and the presence of intralabial barbel. The other species 

 that have been referred to it by naturalists do not appear to be congeneric, 

 but are rather the types of several quite distinct and well marked genera. 

 The genus as now limited still contains nine of the known species.
