lar; both the terminal and lateral rostral tubercles are studded with 
stronger. spinules. 
The interdorsal space is much shorter than. the orbit. The second 
dorsal spine is armed with 34 denticulations. 
The coloration in alcohol is mostly blackish-brown, but is much 
lighter on the upper half of the trunk and head and black over 
the coelom. The fins are all black, the ventral and anal black. The 
buceal and branchial cavities are blackish, becoming abruptly light 
around the inner margin of the upper jaw. The silvery peritoneum 
is punctate with black and thinly coated with purplish brown. 
L. decimalis is sharply distinguished from its close ally, L. pumi- 
liceps, in the number of ventral rays, 10 instead of 11 to 18, in the 
even blunter head, and in certain proportions quite strikingly shown 
by comparison of the tables of measurements we have prepared for 
each species. In decimalis the following measurements are de- 
cidedly shorter: the suborbital width, the distance between the 
orbit and the preopercular margin, the length of the snout and of the 
barbel, and the interdorsal space.
