rately convex, willi the regions weJl deHned. The surface 

 is mostly covered with large granules, which, however, are 

 not crowded, and Avhich become tuberculiform, or sub-spini- 

 form, on the sides of the branchial regions, and are more 

 marked as follows : — Two mid-gastric, one on each side latero- 

 gastric, one on each epibranchial region, one each median 

 on the cardiac and intestinal regions, and two latero-intes- 

 tinal. The inter-orbital space is slightly raised above the 

 orbital borders, and bears some small red granules, a shal- 

 low transverse sulcus divides this from the gastric region, and 

 also sulci separate it from the orbital borders. 



The rostral horns are small, M^ell separated, divergent, 

 acute, horizontal!}^ projecting, sub-cylindrical, tapering, and 

 slightly curved inwards; externally they bear a few very 

 minute teeth, and internally some long corneous bristles. 



The eyes are small, the peduncles short, in almost com- 

 plete orbits, and are slightly visible when retracted. The upper 

 orbital border has the anterior portion arcuated in the ver- 

 tical direction; the posterior end, however, is not spined. A 

 small hiatus separates this end from what I have called else- 

 wdiere the intermediate spine of the upper orbital border; 

 external to this is another process, which corresponds to 

 the post-ocular spine separated only from the former by 

 a closed fissure. The lower orbital border is marked by two 

 closed fissures. 



The hepatic regions are depressed, projecting, and more 

 or less lobate, separated from the branchial regions by nar- 

 row V-shaped clefts of the margin. The postero-lateral and 

 posterior margins are rounded and thickened. 



The anterior margins of the fossettes reach close to the 

 margin of the front; the lower halves of their external mar- 

 gins are formed by the basal antennal joints. 



The basal antennal joint is moderately large, with a 

 strong outer lobe, or branch, which forms part of the lower 

 orbital border; it narrows slightly towards the distal end, 

 and is without distal spines. The second and third pedun- 

 cular joints are small, and the flagellum minute. The second 

 peduncular joint springs from the anterior angle of the orbit, 

 there being no closed fissure, caused by an upper pressure 

 of the end of the basal joint against the upper orbital 

 border, as in Parmnifhrao^ and other genera. 



The epistome is rather narrow, and a little excavate. 

 The external angles of the upper margin of the buccal frame 

 are very prominent, but the upper margin is depressed medi- 

 anly. 



The sub-hepatic region is separated from the sub-orbital 

 by a slight excavation, and from the pterygostomial by an
