990 THE VOYAGE OF H.M.S. CHALLENGER. 



In the details of the mouth -organs and the limbs, apart from those which have been 

 just specified, the specimen agreed so nearly with Liljeboryia haswelli, obtained in the 

 same dredging, that recapitulation seemed unnecessary. 



Locality.— Station 162, off East Moncceur Island, April 2, 1874; lat. 39° 10' 30" S., 

 long. 146° 37' 0" E. ; depth, 38 fathoms; bottom, sand and shells. 



Remark. — The specific name refers to the comparative paucity of notches and teeth 

 in the body and limbs of this animal. 



Family Pakdaliscid^, G. 0. Sars, 1882. 



In 1870 Boeck instituted the Pardaliscinae as the eighth subfamily of the Ganimaridse, 

 and in his subsequent work transferred the group to the Leucothoidse as the fifth sub- 

 family, but without altering the definition, and in each case assigning the same three 

 genera, Pardalisca, Halice, Nicippe. Sars in 1882 changed the subfamily into the 

 family Pardaliscidse. Boeck gave the following definition : — 



" Upper Lip broad, insinuate below [distally]. 



" Mandibles without molar tubercle, not alike, apically dentate ; one with, the other 

 without, an accessory plate ; the palp three-jointed ; its second joint elongate. 



" First Maxillae with the palp tolerably broad, apically furnished with many teeth ; 

 the inner plate nodi form. 



" Second Maxillae with narrow plates. 



" Maxillipeds with the inner plates little or obsolete, the outer plates either broad 

 but rather short, or narrow ; the palp elongate, narrow ; the last joint unguiform. 



" The body thick, inflated, with small side-plates. 



" Upper Antennae slender, with an accessory flagellum ; the peduncle very short ; the 

 anterior joints of the flagellum in the male coalesced and together forming a large joint, 

 furnished on the inner side with bundles of setse. 



" First and Second Gnathopods of the same shape. 



" First and Second Peraeopods strong, the third joint short. 



" Fourth Peraeopods longer than Third, Fifth than Fourth ; in these three pairs the 

 first joint not strongly dilated ; the finger long. 



" Uropods biramous ; the rami almost equal in length ; those of the third pair 

 laminar. 



" Telson elongate, cleft." 



Buchholz in 1874 expressed the opinion that in Pardalisca both mandibles possess a 

 secondary plate, but he was probably misled by observing a broad spine on- the right 

 mandible worn down by use to a stumpy condition, suggestive of its being a plate instead 

 of a spine. Bruzelius in describing the right mandible of Pardalisca cuspidata, Kroyer,
