30 A REVISION OF THE ASTACIDA. 
The types of C. Lecontei came from Mobile, Ala. The specimens from 
other localities assigned to this species by Hagen, on page 48 of his Mono- 
graph, certainly do not belong here. The specimens from Beaufort, N. C., 
and Root Pond, Miss., are C. Blanding. The female from Milledgeville, Ga. 
(No. 246) ill agrees with the types, on account of the shortness of the acu- 
men of the rostrum (the rostrum being like that of C. Blandingi’), the short 
and broad antennal scales, breadth of the hand, etc. Of the three young 
specimens, one is C. spiculifer, the others are too small to be determined 
with any certainty. The three specimens from Pensacola, Fla. (No, 249) 
are young (one female, two males), and resemble C. Leconte: only in the short- 
ness of the posterior portion of the carapace and the width of the areola; in 
other respects, they are like the smooth form of C. Blaudlingii, var. acuta. 
There is no lateral spine on the carapace, and the telson is bispinose. 
Besides the Mobile types, I have found but one other specimen of this 
species in the Museum, a young female in a jar with C. spiculifer (Cat. No. 
172), from Athens, Ga.

This species is known only through a dry type specimen in the Museum 
of the Academy of Natural Sciences of Philadelphia. Le Conte’s description 
of the species is as follows : — 
“A. angustatus. — Rostrum concavum, valde acuminatum, utrinque versus 
apicem fortiter et acute unidenticulatum. Lamina antennalis pedunculum 
antennalem «wquans. Cephalothorax punctatus, parcius ad latera, adeo ut 
Vix paucis punctis notatur, linea ordinaria apice spina armata. Thorax totus 
punctatus, parcius ad latera, tuberculis vel granulis nullis. Areola suturalis 
lata. Dorsum sicut in prioribus [i. e. glabrum seriebus parvis punctorum 
transversalium]. Chela parva, angusta, subeylindrica, punctata, sine tuber- 
culis aut granulis, excepto margine interiore qui paucis denticulus incon- 
spicuis instructus est, digiti recti punctati carinati. Carpus glaber, punctis 
tribus vel quatuor. Brachium glabrum, spinulis paucis latere superiore : infe- 
riore seriebus duabus spinarum, quarum dus anteriores majores et longiores. 
Caude lamella intermedia utrinque trispinosa.
