Talorchestia pravidactyla, 5^. nov.^ Plate V., fig. 5. 



Male. — Superior antennae scarcely so long as the cephalon and 

 the first segment of the pereion ; flagellum as long as the last 

 two segments of the peduncle, composed of seven articuli. Inferior 

 antennae more than thi-ee-times as long as the superior pair ; last 

 segment of the peduncle more than twice as long as the penulti- 

 mate ; flagellum as long as the last segment of the peduncle, of 

 21 articuli. Anterior gnathopoda with the propodos broader 

 distally than proximally, the infero-distal angle produced into a 

 short narrow process ; palm transverse, concave ; dactylos acute, 

 rather longer than the palm. Posterior gnathopoda having the 

 propodos large, heart shaped, the palm oblique, defined by a 

 blunt tooth, with a second tooth close to it on the distal side, and 

 a rounded elevation about the middle ; dactylos geniculate, its 

 apex lying between the two palmar teeth when the hand is closed. 

 Last pair of pereiopoda with the bases dilated posteriorly. 



Female. — Inferior antennae much smaller than in the male. 

 Anterior gnathopoda with the carpus much longer and broader 

 than the propodos, the latter about twice as long as broad, rather 

 narrower at its distal, than at its proximal end. Posterior 

 gnathopoda with the propodos narrow, thrice as long as broad, 

 the dactylos very short, inserted nearer the distal end than the 

 middle of the ventral border of the propodos. Length 13/20 in.
