210 Notes on North American Crustacea. 



Crust, ii. 1554), It is, however, distinguished by the character 

 of the frontal margin, which is grooved so as to appear double. 

 Very common on the Florida Keys. 



Clilorofliiis maculatus, nov. sp. 



The following description is drawn up from a single female specimen, 

 the only one yet received. Carapax yellowish, with numerous brown 

 spots; — narrow, evenly convex, areolated ; lobules rather prominent 

 anteriorly and antero-laterally, with nearly smooth surfaces. No trans- 

 verse ridges. Surface posteriorly glabrous. Antero-lateral teeth four 

 in number (excluding angle of orbit) equal, small but sharply promi- 

 nent ; interspaces broad, concave. Front prominent, sublaminiform? 

 four-toothed ; middle teeth broad ; orbital teeth prominent. A tooth on 

 the subhepatic region just beneath the first of the four antero-lateral 

 teeth. Chelipeds short and stout, spotted with red ; meros spinulose 

 above ; fingers short and stout, with large apices deeply spoon-shaped. 

 Ambulatory feet with the last three joints very spinulose and hairy 

 above. Length of carapax, 0.625 ; breadth, 0.84 inch. 



It is much narrower in proportion than any other Chlorodius 

 of the West Indian province. 



Found at the Tortugas, Fla., by Capt. Woodbury. 



Panopeiis transTersus, nov. sp. 



Carapax very broad, moderately convex, naked, smooth except near 

 the margins anteriorly, where it is minutely rugulose transversely, or 

 granulated. Regions scarcely defined. Surface not uneven near the 

 antero-lateral teeth. Front wide, scarcely at all prominent ; margin 

 somewhat undulated, the two lobes being curved and not straight or 

 truncate. Antero-lateral margin divided by slight incisions into four 

 teeth as in P. crenatus ; — the first tooth, composed of the angle of the 

 orbit coalesced with the second normal tooth, is entire and slightly con- 

 vex in outline. Chelipeds minutely granulated or rugulose above; a 

 tooth on the inner edge of dactylus at the base. Feet and inferior surfaces 

 of the body pubescent. Terminal joint of the male abdomen small.
