FISHERY BULLETIN: VOL. 72, NO. 3 



next tributary upstream. The material, though 

 "float," apparently washed out of the lower bed of 

 the "Virginia" St. Marys Formation, which out- 

 crops along this beach. Lauck W. Ward, 1961, on 

 loan from Warren C. Blow, Paleontology and 

 Stratigraphy Branch, USGS. Three immature 

 specimens ofCallinectes. Two females with broad 

 sternites and triangular abdomen exposed; (A) a 

 half-grown individual with fragmented abdomen 

 distorted (abdomen length about 29 mm from 

 posterior edge of exposed segment 3 to estimated 

 tip of telson); (B) a much smaller individual with 

 incomplete abdomen (abdomen length about 12 

 mm from posterior edge of exposed segment 3 to 

 estimated tip of telson; (C) cephalothorax of an 

 immature individual about 45 mm wide, with 

 broad sternal plates as well as areolations of 

 carapace suggesting C. sapidus, frontal and an- 

 terolateral teeth missing, abdomen unexposed, 

 shape of telson suggesting a female. 



USGS 25275. "Road fill" NW side of Virginia 

 hwy. 360, along both sides of Manquin Creek, 

 King William Co. , Va. Material is ' 'spoil ' ' thought 

 to be derived from nearby road cut(s) during con- 

 struction of addition to hwy. 360. Age unknown, 

 probably Yorktown Formation; Late Miocene. 

 Lauck W. Ward, 1961, on loan from Warren C. 

 Blow, Paleontology and Stratigraphy Branch, 

 USGS. Large, complete right palm (dorsal length 

 about 30 mm), propodal finger, and mold of dactyl 

 broken out of a concretion; palm heavily ridged, 

 facets between ridges reticulated as in C. retic- 

 ulatus (internal mold of hand), but remnants of 

 exoskeleton externally smooth except for granules 

 on ridges; portion of finger remaining resembling 

 Callinectes with proximal enlarged tooth on dactyl 

 and molar apparatus on propodal finger. The palm 

 is compressed in preservation, but appears as 

 broad in restoration as a modern Callinectes. 



USGS 3859. Pleistocene (Miocene?), "tonged up 

 in the Rappahannock River near the Chesapeake 

 Bay by an oysterman" and sent to the Smithson- 

 ian Institution in 1902 by W. McD. Lee. Flat- 

 tened partially crushed central portion of an adult 

 male C sapidus, including part of carapace with 

 regions exposed and sternum with abdomen miss- 

 ing. The dark color of the specimen only suggests 

 similarity to other Pleistocene (Miocene?) mate- 

 rial from the 'area of origin, for exact horizon is 

 unknown. 



USNM 371729, Pleistocene, Broadwater, Va., 

 R. Phillips. A large adult male fragment consist- 



ing of a deformed carapace (length 67, width at 

 base of lateral spines 127 mm) along with a right 

 cheliped lacking fingers. The chela is disarticu- 

 lated. Shape of abdomen, carapace, and carpus of 

 cheliped with no internal spine indicate C. 

 sapidus. 



Seven lots from the Pleistocene, Wailes Bluff, 

 St. Marys Co., Md., treated in part by Rathbun 

 ( 1935) and Blake ( 1953), are similar to Modern C. 

 sapidus but lack definitive characters. 



USNM 145356. Talbot Formation, Bd. 1 (of 

 Mansfield), 1937, S. F. Blake. Immature male 

 with carapace and sternum exposed. 



USNM 146701. Frank Burns, 1886, Stn. No. 

 2032. Portion of left minor dactyl and right pro- 

 podal finger. 



USNM 371726. Talbot Formation, L. W. 

 Stephenson, W. C. Mansfield, and W. P. Popenoe, 

 26 June 1925, (10902). Portion of left propodal 

 finger and hand, and nearly intact right propodal 

 finger. 



USNM 371727. Talbot Formation, W. C. 

 Mansfield, 8-12 June 1920 (8932). Fragments of 

 a left chela (propodus), tips of two fingers, and 

 fragments of a minor chela. 



Uncatalogued lot. (Bd. 1), R. J. Taylor, 15 June 

 1941. Mostly fragments of four right propodal 

 fingers, six left propodal fingers, and one complete 

 right dactyl. 



Uncatalogued lot. (Bd. 1), R. J. Taylor, 15 June 

 1941. Three immature female and one immature 

 male fragmentary sterna. 



Uncatalogued lot. Pamlico Formation, W. E. 

 Salter. Two dactyls from right and left chelae. 



Five lots from Pleistocene, Cape May and At- 

 lantic Counties, N.J., similar to modern C. 

 sapidus. 



USNM 371930. Cape May Formation, Stone 

 Harbor, H. G. Richards. A short section of finger. 



USNM 371933, Cape May Formation, Two Mile 

 Beach, H. G. Richards. A short, stocky propodal 

 finger with well developed molar complex. 



USNM 371934. Cape May Formation, Two Mile 

 Beach, H. G. Richards. Five central portions of 

 right propodal fingers of half- to full-grown indi- 

 viduals, three central portions of left propodal 

 fingers of comparable size, two proximal portions 

 of probable left dactyls of large crabs, and three 

 other pieces possibly broken from above. 



USNM 371936. Cape May Formation, Two Mile 

 Beach, H. G. Richards. Tooth row and tooth sock- 

 ets on finger, probably a dactyl.
