proportion with C%im.œra jordanl ; upper lolx» of caiulul .slii;]illv 

 lower than the lower lobe as in Cklmœra owsloni ; l)0tli lobes 

 high as in Cliimœra milsukuril or Cliîmœra oivstoni. Height 

 of upper lobe measured perpendicular to base 10 to 11 times 

 in head. Lower lobe extends more posteriorly behind upper 

 lobe as usual ; the lobe, gradually diminishing in height ante- 

 riorly, passes into the inconspicuous anal without a notch. 



Pectoral pointed, not falcate, its posterior margin almost 

 straight, its lower angle broadly rounded, its tip scarcely reaching 

 to ventral (although the exact length of pectoral can not be 

 determined OAving to the defective state of preservation). Insertion 

 of ventral fin midway between tip of head and dorsal notch, its 

 posterior margin slightly rounded or rather truncated ; external 

 angle of the margin acute, but its inner angle rounded. In the 

 median line behind the ventrals is a fatty organ, longitudinally 

 grooved. Distance between origin of second dorsal and upper end 

 of the insertion of pectoral a little shorter than the distance 

 between the latter and the insertion of ventral, but almost equal 

 to the distance between the lower end of the insertion of pectoral 

 and the insertion of ventral. 



There exists no difference in external features between the 

 male and the female, except in the sexual characters. Cephalic 

 organ directed downwards and forwards, situated on snout in front 

 of eye, its length 31 in head ; on its lower surface about thirty- 

 five recurved spinous denticles. Claspers trifid, its distal parts 

 covered with fine shagreen as usual, its length from insertion 

 1^ in head, its division at a point halfway of the length. Anterior 

 ventral clasping organ armed with four spinous denticles on the 

 inner side.
