Alpheus heterochalis Say, 1818, p. 243: Milne-Edwards, 1837, t. n, p. 356; Kingsley, 1878-79, p. 329,- Herrick, in Brooks and Herrick, 1892, p. 372; Rathbun, 1901, p. 107; Coutiere, 1910, p. 485. Carapace slightly more than half as long as abdomen, slightly compressed and without grooves; front produced into a rounded lobe above each eye; rostrum carinate, the carina not extending back as far as base of eyes talks and the tip falling short of second article of antennule; rostro-orbital depressions passing gradually into dorsal surface. Abdomen compressed, smooth, tapering; telson with subparallel sides and rounded tip; the four movable spines of the upper surface and those of the distal border relatively much weaker than in C. packardii. Eyes relatively small, covered by the carapace. Antennules with inner branch filiform, about half as long as antenna; outer branch with proximal half expanded. Antennae a little longer than body, very slender; scale with a strong apical spine which slightly exceeds the antennular peduncle; basal segment with a rather weak spine below. Chelae very unequal; the larger one much distorted, the upper and lower siufaces with irregular shal- low grooves and the outer and inner margins deeply notched near base of fingers; dactylus very broad and heavy, strongly curved and with a very large basal tooth. Smaller chela, in the male, mth the dactylus peculiarly flattened and expanded on its outer surface; fingers of small chela, in both sexes, much weaker, less ctirved, and more hairy than in the large chela. Carpal articles of second pair of legs diminish as follows: First, second, fifth, third, fourth. Length of a male, 40 mm.; carapace, 13 mm.; a female, 50 mm. Color, dark, translucent sea green, slightly flushed with purple on sides of carapace; with white markin
