30 A EE VISION OF THE ASTACID.E. 



Tlie types of C Lecontci 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. Blandimiii The female from Milledgeville, Ga. 

 (Xo. 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. Blundm/il), the short 

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

 S25ecimen.s, one is C spiculifer, the others are too small to be determined 

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

 arc j'oung (one female, two males), and resemble G. Lecouicl 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. Blandingil, var. acula. 

 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. Sjiiculifcr (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. anrjudatus. — Rostrum concavum, valde acuminatum, utrinque versus 

 ajjicem fortiter et acute unidenticulatiuu. Lamina antennalis pedunculum 

 antennalem tequans. Cephalothorax punctatus, parcius ad latera, adeo ut 

 vix paucis punctis notatur, linea oi'dinaria apice spina armata. Thorax totus 

 punctatus, parcius ad latera, tuberculis vel granulis nullis. Areola sutm-alis 

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

 transversalium]. Chela parva, angusta, subcylindrica, punctata, sine tuber- 

 culis aut gi'anulis, 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 dua3 anteriores majores et longiores. 

 Cauda3 lamella intermedia utrinque trispinosa.
