Characters.—Merus joints of third and fourth pairs of legs with a spine below 
at the inferodistal angle. Front trispinose; rostrum present and orbital hoods 
each armed with a spine; a sulcus between the eye-shields and the rostrum. 
Large hand sculptured, dactyl closing horizontally; small hand with a superior 
spine above the articulation of the dactyl only, no external spine. Basal spine 
of antennules shorter than first joint of peduncle. Carpus of second pair of legs 
with first and second segments equal. 
Dimensions.—Length of an ovigerous female in the collection of the U. S. 
National Museum from tip of rostrum to end of telson 35 mm.; length of carapace 
and rostrum 11 mm.; length of large hand 19 mm. 
Color.—In alcohol a light flesh tint, much deeper on the large hand. A darker 
spot on the upper surface of the carapace, also on the anterior edge of the first 
two abdominal segments (Lockington). 
Type Locality.‘ ‘Sapience, et au cap Tenare; golfe de Genes’’ (Guérin). 
Distribution.—Farallon Islands, California, to San Bartholome Bay, Lower 
California. Mediterranean; Cape Verde Islands; Bermudas; Porto Rico; Cuba; 
Key West (Rathbun). 
Remarks.—This species lives in pools on rocky reefs at low tide level, and is 
capable of producing, by clapping together the fingers of the larger hand, a 
snapping noise like that which can be made with the finger nail (Lockington). 
Common in sponge masses'and kelp holdfasts (Baker).

Fig. 51. Crangon bellimanus, large hand (after Holmes). 
Characters.—F ront trispinose; rostrum present and orbital hoods each armed 
with a spine; no suleus between eye-shields and rostrum. Large hand sculptured, 
dactyl laminate, closing horizontally. Small hand with a superior spine on upper 
margin at articulation of dactyl and an external spine on outer surface at base 
of dactyl. Basal spine of antennules short, not reaching second joint of peduncle. 
Carpus of second pair of legs with first segment about as long as the next two 
combined, 
Dimensions.—Type: length from point of rostrum to end of abdomen 30.3 mm. ; 
length of larger hand 12.7 mm., of smaller 9.7 mm. 
Color.—The present species may be easily recognized by the beautiful color- 
ing of its hands, which in a dried specimen are orange, with various spots and 
workings of black and white. The carapace presents similar coloration to that 
of the hands (Lockington).
