30 A REVISION OF THE ASTACID.E. 



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. X. C. 

 and Root Pond. Miss., are C. Blandingii. 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. Bhndingii), the short 

 and broad antennal scales, breadth of the hand, etc. Of the three young 

 specimens, one is C. sjuea/i/'r,-, the others are too small to be determined 

 with any certainty. The three specimens from Pensacola, Fla. (No. 249) 

 are voting (one female, two males), and resemble C. Lecontei 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 ^mooth form of C. Bhndingii, 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 ('. spicuHfer (Cat. No. 

 172), from Athens, Ga.

This species is known oidy 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 

 anteunalem sequans. Cephalothorax punctatus, parcius ad latera, adeo ut 

 vix paucis punctis notatur, linea ordinaria apice spina armata. Thorax tot us 

 punctatus, parcius ad latera. tuberculis ve] granulis nullis. Areola suturalis 

 lata. Dorsum sicut in prioribus [i.e. glabrum seriebus parvis punctorum 

 trans versalium]. Chela parva, angusta, subcylindrica, punctata, sine tuber- 

 culis aut granulis. excepto maigine interiore qui paucis denticulus incon- 

 spicuis instructus est, digiti recti punctati carinati. Carpus glaber, punctis 

 t rib us vel quatuor. Brachium glabrum, spinulis paucis latere superiore: infe- 

 eriebus duabus spinarum, quarum duae anteriores majores ei longiores. 

 ('aud;e lamella intermedia utrinque trispinosa.
