more than 1/, the length of head, with 23 serrae on its inner 
edge. Ventrals nearly reaching the origin of anal. Caudal 
forked. Least depth of caudal peduncle 1°/, in the distance 
from the base of last anal ray to that of the middle caudal 
rays, which is 5%/, in the length of the fish. Brownish, with 
2 oblong pale areas on each side of the posterior part of the 
body above the lateral line, the second small and well-separated 
from the first; similar pale areas below the lateral line are 
confluent and the anterior meets that of the other side in 
front of the anal fin; fins more or less blackish at the base 
and with blackish intramarginal bands. Length of single spe- 
cimen known 190 mm. [After Regan, not seen by us].
