436 A. E. Verrill — Decapod Crustacea of Bermuda. 



Eyes large on rather long, stout stalks ; in several specimens the 

 right eye is distinctly larger than the left (see figures). Chelipeds 

 slender ; the merus is nearly as long as the chela ; the fingers gape 

 at base, at least in the male, the thumb being curved downward at 

 base rather abruptly ; outer edge of thumb finely denticulate 

 beyond the curve, edge and tips of finger fringed with short hairs. 

 Entire surface of chelipeds finely spinulosc, with minute flat trans- 

 verse rugiB between the spinules, having ciliated edges. Ambulatory 

 legs also spinulose. The largest specimen has the carapace 7.5™"" 

 long ; 4.5 wide ; length of merus of cheliped, 8™"' ; of chela, 9 ; 

 of dactylus, 4™™. Another specimen had the carapace 7™"" long, 

 4mm -^y^(]g This species is closely allied to 31. simplex Benedict, 

 but Mr. Benedict, who has examined the specimens, considers them 

 distinct. In the latter there are two pairs of spines behind the cer- 

 vical suture ; the rostrum is longer and more slender ; the chelipeds" 

 are longer, and the chelae longer in proportion to merus. Possibly 

 these differences may be due in part or wholly to immaturity. 



Seven specimens, No. 893, were dredged in 50 fathoms, on the 

 Argus Bank, Oct. 13, 1905, by the expedition from the Field Museum 

 of Natural Historj^ under Dr. T. H. Bean, to whom it is dedicated.
