species of the genus Podoccrus. Ceplialon with the latenil lobes rather jiro- 

 jecting and evenly rounded at the tip, postanteunal corners produced to au 

 acute point. Anterior paiis of coxal plates considerably deeper than the 

 corresponding segments, and but sparingly sctous; Is* pair raucli smaller 

 than the others, and somewhat tapering distally; 4th paii' rather broad, with 

 the infero-posteal corners angularly produced. Last pair of opimeral plates 

 of metasome almost rectangular. Urosome short and stout, with a few small 

 hairs and spinules dorsally. Eyes of moderate size and oval in form, being 

 l)laced just within the edges of the lateral lobes of -the ceplialon. Superior 

 antenucO about twice the length of the cephalon, joints of the peduncle suc- 

 cessively diminishing in size, flagellum nearly as long as the peduncle, ac- 

 cessory appendage comparatively small and 4-articulate. Inferior antenna:^ 

 with the last 2 joints of the peduncle simple cyliudric, flagellum about half 

 the length of the peduncle. Anterior gnathopoda moderately strong and 

 rather densely setuus, propodos obpyriform, with tlie palm oblique and 

 imperfectly defined below. Posterior gnathopoda much larger and rather 

 elongated, with only scattered small bristles, basal joint subfusiform, the 3 

 succeeding ones comparatively small and nari'ow, propodos extremely large 

 and gradually expanded distally, palm obliquely aicuate and defined below 

 by a very slight angle, dactylus long and falciform. The 2 anterior pairs of 

 pereiopoda of moderate size and rather densely setous; the 3 posterior pairs 

 slightly increasing in length and comparatively strongly built, basal joint 

 of last pair large and lamellar, its posterioi' expansion terminating below 

 in a broadly rounded lobe, and having the edge smooth. Last pair of uro- 

 poda extremely small, outer ramus scarcely longer than the basal part and 

 having the terminal joint quite rudimentary, inner ramus scale-like, with a 

 single apical seta. Telson small, lateral lobes not diverging, each with a 

 single apical spine. Length of adult female 11 mm., of male 13 mm. 



Bcmarks. — This is the only as yet known species of the genus, the 

 form named by Dr. Grimm Pandora coeca being, as above stated, not con- 

 generic. 



Description of the female. — The lengtli of fully adult, ovigerous speci- 

 mens is about 11 mm. 



The form of the body (see fig. 1) is somewhat slender and scarcely at 

 all compressed, the back being broadly rounded and quite smooth through- 

 out. On the whole it bears an unmistakable resemblance to that in some 

 species of the genus Podocerits, or rather Ischyrocerus ; heuce the specific 

 name proposed by Dr. Grimm. 



Tlie cephalon is not fully so long as the first 2 segments of the meso- 

 some combined, and forms (see fig. 2) a slight angular projection in front.
