346 M. J. Batltbun — Fossil Crab from Port Toicnsend. 



separates the upper surface of the orbit from that of the front. 

 Surface of carapace granulated, granules coarser on the sides 

 of the branchial regions, absent or scarce in the depressions 

 and on the cardiac region and behind the margin of front and 

 orbit. Edge of front and orbit granulated, granules placed 

 irregularly, not all in one row. Next to the orbit, the antero- 

 lateral margin appears straight and oblique for a distance a 

 little greater than the width of orbit, after which there are two 

 strong projecting teeth, the first being the wider. Behind 

 these teeth the lateral margins are nearly straight and parallel 

 for a way, then curve gradually into the posterior margin, 

 which is broken away from the single specimen. 



Details of the chelipeds are not easy to make out. The 

 chelipeds are bent and similarly placed, so that the wrist 

 nearly touches the larger anterolateral tooth of the cara- 

 pace ; in this position the larger cheliped reaches to a 

 point approximately in line with the middle of the body 

 while the smaller cheliped reaches to the middle of the orbit. 

 Yery little of the merus is visible beyond the carapace ; the 

 carpus is rounded, without evidence of an inner tooth ; the 

 manus is apparently thick, and the movable finger is stout ; no 

 prehensile teeth are visible ; propodal finger absent from the 

 large cheliped, crushed and indistinct in the small one. Sur- 

 face of chelipeds granulate, as also of the long merus joints of 

 two ambulatory legs, which are all that is left of those append- 

 ages.
