lobate teeth, which, iu counection with the proportionately greater 

 length of the carapace, readily distinguishes it from any other species.

Carapace broad, transversely rugose; regions well defined, but not 

 protuberant; front rather narrow and but little projecting; margin 

 seen from above nearly straight and obliquely truncated or beveled, the 

 beveled surface being granulated; sui)raorbital fissure distinct; antero- 

 lateral teeth normal in number and rather prominent; subhepatic re- 

 gions granulated; a slight tuberculiform prominence beneath the first 

 anterolateral tooth ; chelipeds smooth ; surface microscopically punc- 

 tated.

Edwards's figure shows the front broad, the antero-lateral margin 

 lobate, the fourth tooth scarcely perceptible. The appearance of the 

 carpus is something like that of ovatus from Lower California. 



6. Panopeus africanus A. Milne Edwards. 



Panopeus africanus. A. Milue Edwards, Aun. Soc. Entotn. France (4), 7, p. 276, 

 1867; Miss. Sci. au Mexique, pt. 5, i, p. 308, 1880. E. J. Miers, Challenger 

 Eept., Zool., XVII, p. 129, 1886. 



A. Milne Edwards says of this species that it is much like chilensis, 

 but the front is less advanced, the carapace more granulate, the antero- 

 lateral teeth are directed more outward and less forward, and lastly, 

 the feet are much more pubescent than in chilensis.

Carapace transversely flat, longitudinally convex; areolatious well 

 marked. Antero-lateral teeth upturned: front slightly prominent, 

 nearly horizontal, edge thin ; sinus of coalesced tooth rounded ; remain- 

 ing teeth rather prominent, triangular, thickened along the anterior 

 edge. Chelipeds with carpi rugose externally. Larger hand stout, 

 fingers short, widely gaping, irregularly toothed within, and with a 

 stout tooth at the base of each finger, the one on the dactyl shutting 

 just within the other. 



Length of carapace in the male, 8.4 millimetres ; breadth, 11.5 mill-
