442 BULLETIlSr 129, UNITED STATES NATIONAL MUSEUM 



tooth on dactyl just behind middle of gape; between this tooth and the 

 tip one or two minute, acute teeth, and on the fixed finger three or 

 four such teeth. On the ambulatory legs the merus, carpus and pro- 

 podus are lobed on their distal margins; the merus and carpus have 

 several dorsal lobes, somewhat biserially arranged, while the propodus 

 has but one dorsal lobe, near its middle; this article diminishes rapidly 

 in length from first to last leg, and is nearly twice as long in first as in 

 last. The distal half of the dactylus is strongly curved; a few small 

 spinules beneath; horny tip long, light-colored. 



Measurements. — Male (46079), total length of carapace 8.7, width 

 of same with spines 10, without spines 9.3 mm. 



Range. — From Cape St. Lucas, Lower California, Mexico, to 

 Panama. Miers ^^ gives " California," probably an error for ''Lower 

 California."

 (3 ovigerous), cotypes (1226, M. C. Z.).

 Orcutt; 4 males, 2 females (46079).

 (part; not pi. 46, fig. 2). 



Diagnosis. — Front (in advance of fronto-orbital sinus) less than 

 twice as broad as long. One or two antero-lateral, branchial, mar- 

 ginal spines. A lateral, as well as a dorsal, lobe on the posterior sur_ 

 face of the propodus of the ambulatory legs. Third (or second free) 

 article of antenna short and stout. 



Description. — Compared to T. cristulipes, the carapace is relatively 

 longer, the lateral angle more pronounced, so that the carapace is 

 less rotund and more triangular; the surface has more granules and 

 fewer tubercles and spines. The crescentic branchial elevation either 

 side of the cardiac region is wider and more swollen. There are only 

 two antero-lateral marginal spines, one at the lateral angle and one in 

 front of it, which is exceptionally replaced by a tubercle. The ante- 

 rior branchial spine and the hepatic spine of cristulipes are replaced 

 by tubercles. The postero-lateral spine is of good size; in front of it 

 is a tubercle which with the three marginal spines forms a parallelo- 

 gram.
