PLATE I. (Crustacea, Plate LXV.) 

 Pomatocheles balssi, n. sp. 



cT . Dorsal view of male specimen magnified, the telson folded out of sight. 



T., urp. Dorsal view of telson and uropods. This figure and the peraeopods on 

 the same scale as the full figure, the rest more highly magnified. 



a.s., a.i. The first and second antennae, flagellum of the second incomplete. 



m., mx. 1, mx. 2, mxp. 3. Mandible, first and second maxillae, and third 

 maxilliped. 



prp. 1,1,2,5. Both members of the first pair in their relative positions, but the inner 

 side of the large left cheliped is shown and the outer of the smaller right- 

 hand one. The peraeopod marked prp. 2 is open to a little doubt, as, 

 besides being detached, it was the only one present of the three inter- 

 mediate peraeopods, and may therefore be the third ; the fifth peraeopod 

 was in position when received. 



pip. 1, 2. The first pair of pleopods and one member of the second pair.
