TATHICARPUS, gen. nov. 
Form more or less robust ; body compressed, elevated 
in front, rapidly tapering posteriorly. Head large, longer 
than deep. Skin dotted with small tubercles, separated 
from each other by a naked interspace, and each bearing a 
bifid spinule. Head and body with cutaneous appendages 
in varying number. Mouth protractile, with moderate, 
subvertical cleft ; maxillary thin, flexible, remiform, with 
a strong median longitudinal ridge, extending far beyond 
cleft of mouth. Jaws, vomer, and palatines with strong 
unequal, cardiform teeth ; tongue smooth. Eyes moderate, 
with well developed supracilary ridge ; infraorbital groove 
deep, naked. Gill-opening a rather large oval orifice, 
pierced at the end of a prominent papilla, and situated 
below and behind the inferior axil of the pseudobrachium. 
Fins spinulose with or without cutaneous appendages : dorsal 
spine erect, mobile, the two last membraniferous ; rostral spine 
slender, long, inserted upon a small bony tubercle above
