Addison E. Verrill, 



legs of the first pair are about twice as thick as the second and 

 third, their propodus is swollen and long-ovate, not angular below. 

 The fifth legs carry the male organs near the inner ventral edge 

 of their basal segment; the organ is nearly circular with a 

 depressed central area, at the summit of a low, verruciform 

 elevation. 



The basal segments of the legs are strongly sculptured and 

 verrucose; the verrucse are obtusely rounded and mostly stand in 

 single rows on the summit of the ridges. The sternal somites are 

 much thickened, with deep depressions between them ; each bears 

 a pair of rather large, obtuse, conical spines partially covered, like 

 the spaces between them, with low or flattened and relatively incon- 

 spicuous granules. 



The epimeral grooves of the abdominal somites are well marked. 

 The lateral borders of the second somite are but slightly produced 

 downward, but are large arid much thickened on the outer edge and 

 bear about seven blunt tubercles. The next three have short thick 

 lobes, crenulated irregularly. The posterior ventral ridges of the 

 second to fifth somites are sharp and finely serrulate. 



Small, slender, thin, biramous pleopods are present on the second 

 to fifth segments, but are very small on the fourth and fifth. The 

 under sides of the legs and of the abdominal somites are covered 

 with small, flattened granules bearing a few very short and small 

 hairs. ' The under side of the carapace is closely covered with 

 large, rounded granules, diminishing in size anteriorly. The 

 under sides of the antennal segments are covered with small pits 

 or puncta, each bearing one, or very few, very short hairs, too 

 small and too scattered to obscure the surface, and a few small 

 granules on the basal parts. 



The females, several of which carried large numbers of small 

 eggs, are smaller, but have essentially the same proportions and 

 ornamentation. Their colors seem to have been rather lighter, 

 with more orange above. The legs of the last pair are relatively 

 somewhat longer, with well-formed chelate tips, in the females. 



According to Mr. A. Hyatt Verrill, this species, as observed by 

 him in Dominica I., is very sluggish and walks very slowly, but it 

 can use its powerful abdomen vigorously, for propulsion and 

 defense. It is used there as food by the natives and its flesh is of 

 excellent flavor though somewhat watery. It resembles that of a 

 crab more than that of a lobster.
