 Glanconome leucopis, Kroyor, Nat. Tid.ssl<r. 2 R. Bd. 1, 1 p. 4(il. 



Body comparatively strongly built, with the segments of mesosome 

 sharply defined and transversely suleate, tl)ose of metasome having on each 

 side a rounded prominence. Cephalon rather broad, and produced in fiont to 

 an acute rostrum, lateral lobes somewhat projecting between the antenna^, 

 and obtuselj^ rounded at tlie tip. Anterior pairs of coxal plates acutely 

 produced in front; Hth pair with the anterior lobe triangular in form and 

 deeper than the preceding pairs, its inferior edge fringed with ciliated setfE. 

 The 2 anterior pairs of cpimeral plates of metasome acutely produced at the 

 lateral corners; last pair somewliat less deep than the preceding pair, and 

 having the lateral corners produced to a strong recurved dentiform projection 

 defined above by a deep sinus, posterior edge forming above the sinus a 

 I'oundcd setiferous expansion. Eyes imperfectly developed, and replaced on 

 each side by a small ]:)atch of an opaque whitish pigment. Superior antennse 

 near'ly equalling in length "/a of the body, -w\ joint of tlie peduncle the 

 longest, 3rd joint exceeding half its length, flagellum somewhat, shorter 

 than the peduncle, and composed of about l(j articulations, accessory 

 appendage well developed, though rather narrow, and 5 articulate. Inferior 

 antenntB somewhat shorter than the superior, but much more strongly built, 

 e.specially in the male, antepenultimate joint in that sex very broad and 

 expanded at the end to a rounded lobe, penultimate joint considerably 

 thickened at the base, flagellum nearly half the length of the peduncle, and 

 composed of about 10 articulations. Both pairs of antennse provided pos- 

 teriorly with scattered fascicles of sleiuler bristles. Maxillipeds having tlie 

 1st segment of the basal part expanded at the end on each side to a lingui- 

 form, ciliated lobe. Anterior gnathopoda in female rather powerful, with the 

 carpus comparatively short and produced below to a small, setiferous lobe, 

 propodos large and broad, with the palm rather oblique, and defined below by a 

 distinctly projecting angle armed with several strong spines, dactylus densely 

 setous outside and minutely denticulated inside ; anterior gnathopoda in male still 

 more strongly built than in female, with the propodos comparatively broader, 

 and expanded below to a rounded lobe defining the palm posteriorly, the 

 latter minutely serrulate and distinctly angular above the middle. Posterior 

 gnathopoda of same structure in tlie two sexes, being much feebler than the 

 anterior and densely setous, propodos narrow oblong and about the length 

 of the carpus, palm very short and transverse. Pereiopoda moderately
