tenuipes have not been described and the differences of the buccal 

 pieces of the specimen at hand from those of P. cuspidata Kr0yer 

 (Sars, 1895, pi. 141) indicate that the mouthparts of P. tenuipes may 

 also differ from those of P. cuspidata and P. marionis. Most of the 

 posterior end of P. marionis has not been described. The specimen 

 at hand differs from P. tenuipes mainly in the absence of eyes but the 

 length of article 6 on gnathopod 1 appears to be relatively shorter in 

 Pardalisca species than in P. tenuipes. There are slight differences 

 in the proportions of various articles of the pereopods of the two 

 species. Uropod 3 is missing on the specimen at hand and the right 

 mandible resembles that of P. marionis more than that of P. cuspidata 

 because of the presence of two large submarginal spines. Maxilla 2 

 resembles that of P. cuspidata more than that of P. Tnarionis.

Diagnosis. — Upper lip short, broad, medially notched, lobes shallow 

 and nearly symmetrical ; rostrum small, distinct, blunt, lateral cephalic 

 lobes massive, mammilliform; right mandible with three large blunt 

 teeth, one bifid, lacinia mobilis bifid, one spine in spine row and a 

 setose ridge occurring proximal to it ; left mandible with four minute 

 distal protuberances, lacinia mobilis broad, minutely serrate, two spines 

 in spine-row with setose ridge proximal to spines; mandibular palp 

 long, article 3 longer than 2, apically setose; lower lip like that of 

 Pardaliscella hoecki (Malmgren) (in Sars, 1895, pi. 143, fig. 2) ; inner 

 plate of maxilla 1 not discovered, otherwise like P. hoecki; lobes of 

 maxilla 2 broad and short ; maxilliped like that of P. hoecki but dactyl 

 elongate; coxae 1-4 elongate, quadrate, coxa 5 large, not bilobed, ovo- 

 triangular, coxa 6 small, slightly bilobed, posteroventral corner with 

 small tooth, coxa 7 small, short, broad, with small posteroventral notch 

 and seta ; gnathopods like those of Ualice Boeck, fifth articles medium 

 in length, distinctly separated from adjoining articles, posteriorly 

 truncate and trapezoidal in outline, sixth articles slightly longer than 

 fifth, tapered distally, slightly concave posteriorly, posterior margins 

 bearing stout, biplumose spine-setae, dactyls long, nearly three fourths 

 as long as sixth articles; pereopods 1 and 2 with dactyls as long as
