Genus Aspedophoeeia, novum. 



Coxae of the posterior gnathopoda and of the first and second 

 pairs of pereiopoda greatly expanded, deeper than the respective 

 segments, those of the three last pairs of pereiopoda small, that 

 of the third pair bilobed — the posterior lobe larger than the 

 anterior. Antennae simple ; the superior pair shorter than the 

 inferior. Mandibles without an appendage. Maxillipedes with 

 a pointed dactylos. Gnathopoda sub-chelate — the posterior pair 

 much larger than the anterior. Posterior pleopoda uniramous — 

 the ramus uniarticulate. Telson squamiform, cleft to the base. 



This genus differs from Stenothoe, Dana, in having the ramus 

 of the last pair of pleopods uniarticulate ; in most of its characters 

 it approaches AUorchestes — being distinguished from that genus 

 only by the largely developed anterior coxse, and the character 

 of the telson. 



Aspidophoreia diemenensis, sp. un., Plate VI., fig. 2. 

 Superior antennae as long as the cephalon and the first segment 

 of the pereion, rather longer than the peduncle of the inferior 

 pair ; flageUum longer than the peduncle, of about 20 articuli. 

 Inferior antennae with the peduncle stout, the fourth joint the 

 largest; flageUum slightly shorter than the peduncle, of about 

 20 articuli. Anterior gnathopoda with the carpus sub-triangular 

 in outline ; the propodos larger than the carpus, irregularly 

 triangular, palm transverse, deeply concave. Posterior gnathopoda 

 large ; propodos heart-shaped, palm oblique, armed with short 

 bristles. Basa of three posterior pairs of pereiopoda broad, that 

 of the fifth pair much expanded behind ; their anterior borders 

 serrate and armed with setae, the posterior border smooth. Eamus 

 of last pair of pleopoda short, conical,' acute. Telson consisting 

 of two quadrangular scales, separated by a linear fissure. Surface 

 (in the spirit specimen) ornamented with marbled spots of red, 

 brown, and white, and ornamented with numerous, very minute, 

 white dots, arranged in clusters of three or four. Length 4/5 in.
