 "six distinct rods occur on both sides of tho same proinincncc." Pectoral broad, 

 reaching far beyond the origin of the ventral. Ventrals small, nearly equal to 

 first dorsal. No anal lin. Su])racaudal moderately developed, without si)ines 

 on its upper margin; sul)ca\idal nuich lai'ger, longei', and moi-c than twice as 

 deep, origin farther forward near a vertical from the end of the second dorsal. 

 Caudal filament four and one third times the diameter of the eye. Hind margins 

 of pectorals and ventrals convex, outer angles bluntly i-ounded. Lateral line 

 somewhat nearly straight; jugular section meeting the postorbital a short ilis- 

 tance behind the junction of the latter with the suborbital and the angular. 

 Frontal tenaculum of the male with a nuich curvetl stem, agreeing with the 

 convexity of the forehead. Clasjier simjile, slender, reaching the hind margin 

 of the ventral, with a roimded knob beset with prickles at the distal entl.

"Diagnosis. — Adidt male with the snout (measured between verticals 

 from its tip to the origin of the vomerine dental plates) as long as the distance 

 between the dorsal insertions of the pectoral and ventral Hns and somewhat 

 longer than the base of the second dorsal hn. Second dorsal hn with base about 

 half as long as the distance between the gill-openings and the origin of the ventral 

 lobe of the caudal hn. Posterior ventral claspers tenninating in subconical 

 slightly volute clubs. Vomerine dental i)lates deejjly notched on their cutting 

 edges." 



The specimen described was about 45. S inches (IKio mm.) in total length, 

 nearly 34 inches from the end of Ihe snout to the su])racaudal hn. It was taken 

 on the Irish Atlantic SIojjc. The descri])tion as given above would i)lace the 

 species in Harriotta rather than in Khinochimaera. Proliably the type repre- 

 sents a male of IlarrioUa rdlcighana, the largest siiecies of Khinochimaeridae 

 known.
