BRAOHYURA AND MACRURA OF HAWAIIAN ISLANDS. 
925 
The first pair of trunk feet reach to distal third of acicle, carpus one and a half times merus, 
enlarged distally; propodus same length as merus, not larger than distal end of carpus, fingers half as 
long as palm. The left foot of the second pair exceeds the scale by the length of half the propodus; 
it is similar in form and thickness to the first; merus three-fourths as long as carpus, which is twice 
as long as propodus; palm twice as long as fingers. The right foot of second pair in type specimen is 
missing, but the basal joint appears somewhat stouter than that of the left foot. Both feet of second 
pair are missing from second specimen. The third foot reaches end of acicle, the fifth extends only 
to distal third of acicle; in the second specimen these feet are a little longer. 
Dimensions. — Male, length of carapace, 9.5; rostrum, 15.7; abdomen, 31 mm. 
Vicinity of Kauai Island, 528 fathoms, station 3992; 1 male, 1 female (Cat. No. 30556). 
This species in its long rostrum and acicle has great resemblance to a Pandalus. 
Palsemonella tenuipes Dana. 
Palsemonella tenuipes Dana, Crust. U. S. Expl. Exped., I, 582, 1852; atlas, pi. xxxviii, fig. 3 a-d, 
1855. 
South coast of Molokai Island, 8 fathoms, station 3834, one specimen about 11 mm. long, rostral 
formula f; second pair of feet as long as body exclusive of rostrum. 
One imperfect specimen of Palxmonella from northeast coast of Hawaii Island, 77 to 75 fathoms, 
station 4057, has much resemblance to P. tridentata Borradaile. « The rostrum and antennal joints are 
similar; rostral formula f, rostrum more ascending. Only feet of the first and fourth pairs are present, 
both very slender, the fingers of the first pair thin, blade-like, and quite as long as the palm. The 
outer uropod is longer than the inner. 
Palsemonella orientalis Dana. 
Palxmonella orientalis Dana, Crust. U. S. Expl. Exped., I, 583, 1852; atlas, pi. xxxviii, fig. 4 a-d, 
1855. 
South coast of Oahu, surface, stations 3812 and 3921; north coast of Molokai, surface, station 3889. 
Four specimens in all. 
This species has a hepatic as well as an antennal spine; it is not shown in Dana’s figure, but in 
his description of the genus (p. 582, op. cit.) he says: “In both species of the genus here described the 
carapax has two spines below the eye in nearly the same horizontal line.” 
The rostral formula in our specimens is f§-, with one spine behind the orbit; in Dana’s type f. 
In the second pair of feet the carpus is shorter than half the propodus, not shorter than half the 
palm, and the fingers are nearly or quite as long as the palm. The last three pairs of feet have biun- 
guiculate dactyli, as in P. biunguiculata Nobili. 
Palsemonella laccadivensis Alcock and Anderson. 
(PI. xxir, fig. 2.) 
Palxmonella laccadivensis Alcock and Anderson, Jour. Asiatic Soc. Bengal, LXIII, 1894, 157; Ann. 
Mag. Nat. Hist. (7), III, 1899, 4; Illus. Zool. Investigator, Crust., part iv, pi. xxvi, fig. 4, 
1896. 
Vicinity of Kauai Island, 500 to 385 fathoms, station 3989, 1 female. The rostrum is longer than 
in the type, exceeding the acicle, and has thirteen instead of nine spines above, two of them being 
behind the orbit, and three spines below instead of two. Length, 33.2 mm. 
Vicinity of Laysan Island, 222 to 100 fathoms, station 3943. One female laden with eggs is very 
much smaller than the preceding (15 mm. long); its rostral formula is f, the rostrum scarcely reaching 
beyond antennular peduncle.
