MR. E. J. MIERS'S REVISION OF THE HIPPIDEA. 331 



toothed, the raediau frontal notch not wider than deep, and the 

 spine at the antero-lateral angle much longer than in A. oxyo- 

 phthalma. The anterior legs were wanting ; and nothing is said of 

 the form of the tarsal joints of the remaining legs, or of the form 

 of the terminal segment, by De Saussure.

Albunea speciosa, Dana, U.S. Expl. Exp. xiii. Crust, i. p. 405, pi. xxv. 

 fig. 6 (1852). 



This species is characterized by Dana as having the carapace 

 marked with transverse lines, anterior margin either side of middle 

 about 10-toothed, sides of thorax nearly parallel ; peduncles of 

 eyes slender, attenuate ; anterior or upper margin of last joint of 

 fourth pair of legs nearly straight ; terminal segment a little ob- 

 long, quite entire, at apex subtriangular, its sides nearly parallel, 

 sparingly arcuate. Length of carapace 7 1 lines.

This species appears to be well characterized by the form of the 

 eye-peduncles, which are represented in the figure as much nar- 

 rower in their distal than in their proximal half; concave, not con- 

 vex or straight, on their outer margins. The spine at the antero- 

 lateral angle is very small, and does not reach to the anterior 

 margin of the carapace. The form of the tarsal joint of the third 

 pair of legs is not mentioned ; that of the fourth pair is broad and 

 scarcely at all falcate. The terminal segment (apparently of the 

 female) is oblong-ovate. I have seen no specimens of this species. 



Lepidops *. 



Lepidopa, Stimpson, Proc. Ac. Nat. Sci. Phil. p. 230 (1858). 



Eye-peduncles lamellate, compressed, almost squamiform, cornea 

 not visible. Antennules long. Antennae with a very small acces- 

 sory joint, flagellum very short. Third maxillipedes with the fourth 

 joint produced at its antero-external angle into a lobe, which 

 reaches to or beyond the distal extremity of the fifth (penulti- 

 mate) joint. 



By the opposition of the last two joints of the third maxilli- 

 pedes to the lobe of the antepenultimate joint, a prehensile organ 

 is developed similar to that formed in the same pair of limbs in 



* The generic name Lepidopa is more correctly written Lepidops by Stimp- 

 son in his description of L. myops.
