50 ALLAN HANCOCK FOUNDATION OCCASIONAL PAPERS
3 vertical irregular maroon red bands. The anterior of these bands
is bent forwards at right angles in the upper part, sometimes this anterior
line gives off an anteriorly directed side branch, which is placed under
and runs parallel with the forwardly curved part of the anterior band:
the anterior band being thereby more or less F-shaped. The two other
vertical bands have the tips curved more or less abruptly backwards.
The abdominal pleurae are provided with oblique red stripes. A red
spot is present on the eyestalk. The inner margin of the antennular
peduncle is blue. A line of blue dots is visible on the scaphocerite, forming a continuation of the blue line of the antennular peduncle. The
chelipeds are pale pea greenish, becoming china bluish distally. The
articulation of the fingers is orange ochraceous, just like the distal part
of the palm and the base of the fingers. The eggs are pea green." Hedgpeth (1947) gives the following account of the colouration of Texan
specimens of the species: "Macrobrachium acanthurus is greenish
in color with a dirty orange stripe down the middle of the back. The
claws of this shrimp are not so highly colored, and in fact are usually
covered with mud." Hedgpeth's (1949) colour description of the species
is very similar.
Material examined: The Allan Hancock Foundation possesses 2
specimens of this species from:
Florida: Boca Raton, Palm Beach Co., fresh-water canal, June,
1944.
In the U.S. National Museum a large number of this species is
present. It originates from the following localities: Georgia (St. Simon
Sound and Brunswick, Glynn Co.; Cumberland River), Florida (St.
Augustine, St. Johns Co.; Daytona Beach, Volusia Co.; Sebastian,
Indian River Co.; Fort Pierce, St. Lucie Co.; Boca Raton, Palm Beach
Co.; Miami, Dade Co.), Mississippi (Ocean Springs, Jackson Co.;
Biloxi, Harrison Co.), Louisiana (Lockport, Lafourche Parish; near
Grand Isle, Jefferson Parish), Texas (Palacios, Matagorda Co.;
Espiritu Santo Bay, Calhoun Co.; Aransas Pass, San Patricio Co.;
Corpus Christi, Nueces Co.; mouth of Rio Grande), Mexico (Vera
Cruz; Chiapas River near Gutierrez), Nicaragua (Escondido River
near Bluefields), Panama (Puerto Pilon and Toro Point near Colon;
Colon; Mindi; Gatun; Frijoles; Porto Bello), Colombia (Sabanilla=
Puerto Colombia), Venezuela (near Sinamaica; Lake Tule W. of
Maracaibo; Rio Cocuiga W. of El Mene, Falcon Province; Rio Cum-
boto near Ocumare; lagoon near Barcelona; stream near Carupano;
Rio Amana near Maturin; lower Orinoco), Brazil (Pernambuco;
