Panopeus purpureus Lockington. 
Panopeus purpureus Lockington, J. c. vit, 101, 1876; Streets and 
Kingsley, J. c. 1x, 105 (1877). 
This form is very near P. validus Smith, and probably will prove 
to be merely a variety of it. In comparison with Smith’s description 
and with authentic specimens of P. validus brought from the Gulf 
of Fonseca, by J. A. MecNiel, it presents the following differences: 
Carapax smoother, and the granulous ruge less numerous; front less 
prominent and, seen from above, nearly straight; fissures of the orbit 
less evident; tooth at inner angle of orbit below broader and shorter, 
second normal tooth of antero-lateral margin separated from the 
angle of the orbit by a narrower, more triangular notch; notches 
between the remaining teeth narrower, the teeth themselves having 
a distinct elevated margin. Propodus of chelipeds with an obtuse 
crest above ; the tooth on the outer surface of larger hand nearly ob- 
solete, dactylus with a large basal tooth. Ambulatory feet less com- 
pressed than in P. validus.

Panopeus Packardii sp. n. . 
Carapax moderately convex; areolations less prominent than in 
P. Herbst, surface minutely granulous. Front prominent, nearly 
horizontal ; edge thin, arcuate, bilobed, the lobes being separated by 
a shallow groove. Orbits with two fissures above ; post orbital tooth 
separated from the second tooth nearly as in P. americanus Saussure; 
the remaining teeth more acute than in P. Herbstii. External hiatus 
of orbit a narrow fissure. Sub-hepatic tubercle present, small; sub- 
hepatic regions minutely granulate. Chelipeds unequal; meros with 
one or two spines on the superior margin near the middle; carpus 
with a spine on the inner margin; larger hand stout, a rounded tooth 
below the articulation of the dactylus, dactylus with a strong basal 
tooth ; fingers slightly deflexed; smaller hand with the tooth near the 
articulation of the dactylus broader and less prominent, and the 
fingers more strongly deflexed than in the larger hand, dactylus 
without a basal tooth.
