84: Wotes on NortTi American Crustacea. 



tibicen^ — differing onlj in color and in its somewhat more elon- 

 gated hand. The greater cheliped is everywhere reddish-brown, 

 with the exception of lighter margins to the fingers. The 

 ambulatory feet are dark-ohve, almost black, and their terminal 

 joints are annulated near the tip, and sometimes also near the 

 base, with a reddish ring. 



This species might be referred to O. chilensis, with which it 

 agrees in the length of the eyes, etc., but that species is in Gay's 

 Hist, de Chile, Zool. iii. p. 191, said to have " varios tuberculitos 

 sobre las pinzas y la parte vecina de la mano." 



Collected in considerable numbers at Panama by Dr. Suckley. 



Clibanarius Tittatus. 



JPagurus vittatus, Bosc. ; Hist, des Crust, ii. 8. pi. xii.

Hands equal. Ambulatory feet 8-striped longitudinally; with dactyli 

 longer than the penult joint. 



Found at the mouth of the Rio Grande by Dr. Berlandier ; at 

 St. Augustine, Fla., by Mr. Dorman ; and is common at Charles- 

 ton, S. C. 



Clibanarius panamensis, nov. sp. 



Of the same size with C. vittatus, to which it is very closely 

 allied and perhaps identical ; differing but little except in the 

 arrangement of the colors in the longitudinal vittse of the ambu- 

 latory feet. The white vittse are more regularly arranged, 

 equidistant, and more distinct on the inner sides of the feet. 

 There are also more numerous stripes on the meros joint. 

 Lastly, the tubercles of the hands are somewhat more sharply 

 prominent.
