Gen. 10. Podoceropsis, Boeuk, 18G0. 



Syn: Na;nia, Sp. Bate. 

 > Xenoclea, Boeck. 



Form of body re.seiubliiig tliat in the gen. Gammaropsis. Ceplialun 

 witli the frontal part rather produced, and having the lateral corners angular. 

 Coxal plates of moderate size ; 5th pair with the anterior lobe more or less 

 deep. Ej-es well developed, and placed on each side of the frontal part of 

 the cephalon. Antennae rather slender, and .subefpial in length, with elongate<l 

 peduncles, both pairs densely setiferous, the su])erior ones without any trace 

 of an accessory appendage. Anterior lip more or less produced in front. 

 Mandibular palps elongated and densely setous. Oral parts otherwise 

 normal. Grnathopoda very une(jual, the anterior ones being rather feeble, and 

 of same structure in the two sexes, the posteri(jr ones much larger, and very 

 powerfully developed in the male. Pereiopoda normal and more or less 

 slender, the 3 posterior pairs with the basal joint moderately expanded. 

 Last pair of uropoda scarcely extending beyond the others, rami subequal. 

 Telson rounded, tubular. 



Rcmarls. — In .spite of the absolute want of an accessory appendage 

 to the superior antennas, this genus exhibits a very close aftinitj' to the 

 genus Gammaropsis, with which it agrees perfectly in nearly all other points. 

 The genus Nccnia of Sp. Bate is identical with that of Boeck, which was 

 established somewhat earlier. As already pointed out by Prof. Meinert, the 

 genus Xenoclea of Boeck, though placed within a different subfamilj^ cannot 

 pro])erly be distinguished from the genus Podoceropsis, and ought thereftire to 

 be merely regarded as a synonym. The genus comprises 2 Norwegian species' 

 to be described below. The Ncenia midata of Sp. Bate would also seem to 

 belong to this genus. Moreover Dr. Hansen has described an Arctic species 

 as P. LindaMi, and a 5th species has been added by the E,ev. Mr. Stebbing 

 from the Challenger Expedition.
