 Neopanope texana sayi Stunner, 1911, p. 673; Fowler, 1912, p. 400. pi. 121. 



Carapace about three-fifths as long as wide, quite convex, minutely granulate and lightly 

 pubescent, especially near anterior and lateral regions; anterolateral teeth five, of which the first two 

 are coalesced and separated by only a shallow sinus, the third and fourth are larger and directed 

 forward while the fifth is smaller and directed somewhat outward; from the fourth and fifth teeth 

 short, oblique ridges extend inward and backward; front with a very small median notch, each half 

 only slightly sinuate, the entire effect being that a much flattened ciu-ve extending from eye to eye. 



Chelipeds smooth, unequal and dissimilar, carpus with a prominent groove parallel with its distal 

 margin; movable finger of large hand without a large basal tooth. 



Length, 17 mm., width, 22.5 mm. 



Color, usually a dark slaty bluish green, sometimes brown or even buff; fingers black, the color 

 extending well onto the palm. 



In the parts of the harbor which support oyster reefs this crab is abundant. It may also be found 

 among the clusters of ascidians on the wharf piling about the town. The zoea and megalops stages 

 of P. texanus sayi have been fully described and figitfed by E. A. Birge (loc. cit.). 



Genus EURYTIUM Stimpson. 



Eurytium Stimpson, 1859, p. s6.

Cancer limosa Say, 1818, p. 446. 



Panopeus limosus H. Milne-Edwards, 1834-1840, 1. 1, p. 404. 



Eurytium limosum Stimpson. 1859. p. 56: Kingsley. 1878-79, p. 316: A. Milne-Edwards, i83o, p. 332; Rathbun, 1901, 

 p. 41; Verrill, 1908. p. 358; Fowler, 1912, p. 124. 



Carapace about one and one-half times as wide as long, very convex from front to back, nearly 

 plane from side to side, siuiace smooth to the eye but under a lens finely granulate; front about one- 

 fourth the width of carapace, divided into two lobes by a median notch from which a shallow groove 

 runs back over the gastric region; orbital margins somewhat elevated; external orbital tooth coalesced 

 with the first tooth of the anterolateral border, the division between the two indicated by a shallow 

 sinus; anterolateral teeth with raised margins, the second and third rounded at the tip, the fourth 

 more prominent and subacute. 



Chelipeds tmequal and dissimilar, more so in the male than in the female ; meros with a denticulate 

 superior border and a distal spiniform tooth; carpus not grooved; fingers pointed. 



Length of a male, 24 mm., width, 36 mm. 



Color in life: "Carapace a brilliant ptnplish blue; wrist and hand bluish; proximal upper half of 

 movable finger pink; remainder of finger porcelain white; lower portion of chelipeds and also the 

 carpal teeth yellow. " "■ The color of the fingers is not continued onto the palm. 



This crab is common along the coast farther to the south and is said to have been collected as far 

 north as New Jersey. It is given in Kingsley 's list of crustaceans whose range embraces Fort Macon, 

 but is not definitely credited to the Beaufort locality. 



So far as is known it has never been taken here, but it is one of the species for which the collector 

 should be on the lookout. It is said to live in holes which it digs along the margins of salt marshes 

 near high-tide level. Its brilliant coloration should enable one to recognize it at once. 



Having no Beaufort specimens for study the above description was based on a fine male from Port 

 Royal Island, South Carolina, borrowed from the United States National Museum.
