The color patterns suggest an intermediate typo between Pirchid 

 cain'oth'S and HadroiJtcnis aspro. Sides with about nineceen large, distinct 

 black blotches wliich, especially along the middle region, alternate witli 

 smaller ones, these often being tlie ventral ends of more or less well 

 developed, transverse bars. The dorsal side with a series of large quad- 

 rate blotches alternating and anastomosing witli variously developed 

 transverse bars. Tlie color pattern is of the transverse type rather than 

 the longitudinal characteristics of //. aspro and )ii(icrocciili(iIi(iii. In the 

 older specimen this dorsal pattern l)ecomes more diffuse and less regular. 

 Dorsal two-thirds of opercle and the upper part of clieek, black. A dis- 

 tinct black band extends downward and anotlier. more diffuse, forward 

 from the eye. Both dorsals and the caudal hn. barred, pectorals indis- 

 tinctly so; ventrals and anal, plain. A Idack spot at the base of the caudal.

The species is most closely relatt'd to llaiJi-opti-nix (isprn and Hddriiji- 

 tenis riiacrocrphaJiiw. From the former it differs most strikingly in the 

 color pattern, especially that of the dorsal side, which is transverse in
