BRACHYURA AND MACRURA OF HAWAIIAN ISLANDS. 
901 
lateral dorsal row is opposite the antepenultimate of the middle row. The transverse row of large 
light-colored spots on the second to fifth abdominal segments contains six instead of five spots, there 
being two submedian, none median. Telson a little longer than its basal width. Right chela a little 
longer than left; its dactylus is a little shorter, that of the left chela a little longer, than its palm. 
Median rows of tubercles of palm small but distinct; other tubercles of upper and lower surface minute, 
set in a very short coat of pubescence. 
Family STENOPIILE. 
Stenopus hispidus (Olivier). Bandana Prawn. 
Stenopus hispidus Brooks and Herrick, Mem. Nat. Acad. Sci., Y, 1892, 326 and 339, pis. v-im. 
Rathbun, Bull. U. S. Fish Comm., XX, 1900, (1901) 99, pi. ii, and synonymy. 
Young specimens about 20 mm. long, are slenderer than the adult, with relatively longer rostrum, 
about three-fifths as long as remainder of carapace and devoid of lateral spines. Abdomen strongly 
bent at the third segment, which has a prominent median tubercle near posterior end; sixth abdominal 
segment very elongate, three or four times as long as fifth. 
Distribution. — Honolulu; Honolulu Reef and market; Hilo, Hawaii, U. S. Fish Commission and 
H. W. Henshaw; Puako Bay, Hawaii, 1902; south coast of OahuHsland, station 3921, surface; between 
Honolulu and Kauai Island, station 3980, surface. 
Spongicola henshawi, sp. nov. 
(PI. xxiv, fig. 8.) 
Rostrum dorsally serrate with six spines besides one rudimentary, one spine below; over half as 
long as rest of carapace, reaching beyond antennular stalk. A spine below the orbit, and one on each 
side behind the base of the rostrum'. Anterior margin below the orbit armed with spinules; a little 
farther back and parallel, a row of three or four larger spinules. Telson with two longitudinal rows 
of four spines each dorsally, edges spinulous, not reaching end of swimmerets, which are serrulate on 
outer margin. Eyes light olive in alcohol; a few spinules border the corneal margin and arm the 
anterior and dorsal surface of the stalk. Outer margin of acicle finely serrate. Outer maxillipeds 
stout, setose; second pair of legs equal in female, about twice as long as first pair and stouter; both pairs 
smooth; third pair sparingly setose, unequal (in female), much stouter than second pair, only the 
larger one longer than the second leg. Ischium with distal spine. Arm spinulous, a spine near distal 
end on upper and on outer side; wrist not much longer than broad,- cup-shaped, distally spinulous 
above; hand broad, compressed, margins finely serrate, fingers bent down, narrow; a triangular tooth 
on the dactyl fits between one similar tooth and an obliquely truncate basal tooth on the thumb; 
fourth and fifth pairs very long, subequal; dactylus short, bifid; propodites posteriorly setose. 
Length of egg-laden female 26.2 mm. 
One specimen only from south coast of Molokai Island, 169 to 182 fathoms, station 3835. (Cat. 
No. 30538.) Named for Mr. H. W. Henshaw, formerly of Hilo, who has contributed much to our 
knowledge of the Hawaiian fauna. 
Near S. andamanica Alcock , a but differs in longer rostrum, posterior position of spine at base of 
rostrum, longer, slenderer fingers, shorter telson.
