SCHIZOPODS OF THE HAWAIIAN ISLANDS.

supraocular spines agree well with Sara’s account. The only difference is in the antennal scale, 
which, although similar to Sars’s figure, has the oblique truncation of the apex hardly noticeable; it 
is more like fig. 2 on Sars’s plate, than like the figs. 4 and 5. • The scale is generally narrower, with 
three serrations on the outer margin, the first one quite remote from the spiniform tip, but not 
separated from it by an emargination. 
G. bengalensis Wood-Mason (Ann. Nat. Hist. (6) 8, 1891, p. 269), from the Bay of Bengal, 1,748 
fathoms, is said to be near G. calcarata, but to differ, among other points, in the postero-inferior and 
other spines, which are almost smooth, in the antennal scale, which is more emarginate, and in the 
epimeral lappets of the last abdominal segment. 
Stations: 4109, 442-449 fathoms, Kaiwi Channel, 1 male; 4142, 632-881 fathoms, vicinity of Kauai 
Island, 1 male. 
Distribution. — This species was taken by the Challenger in the Arafura Sea, 800 fathoms, and at the 
Philippines (near Talaur Island, south of Mindanao) , 500 fathoms. 
12. Gnathophausia willemoesi G. O. Sars. 
Gnathophausia willemoesi G. O. Sars, Rep. Voy. Challenger, 13, 38 pi., 5 f. 1-6, 1885. Faxon, Mem. 
Mus. Harvard, 18, 1895, 215. 
Our male has the total-length of 52 mm., of which 12 mm. belong to the rostrum. The female 
is 73 mm. long, of which 13 mm. belong to the rostrum; the latter, however, is damaged at the tip. 
The larger of the two specimens examined by Sars was 136 mm. long. Our specimens agree 
completely with Sars’s account of this species. 
Stations: 3887, 552-809 fathoms, north coast of Molokai, 1 male; 4038, 689-670 fathoms, west coast 
of Hawaii, 1 female. 
Distribution. — Banda Sea, 1,425 fathoms (Sars). Panama region: Gulf of Panama, 1,270 fathoms; 
off Acapulco, Mexico, 493 and 664 fathoms; Tres Marias Islands, 680 fathoms. (Faxon.) 
13. Gnathophausia sarsi Wood-Mason. 
Gnathophausia sarsi. Wood-Mason, Ann. Nat. Hist. (6) 7, 1891, 187. 
Our specimens correspond completely to Wood-Mason’s description of this species, with the 
exception of the last sentence, which says: “The telson * * * appears to be more produced at 
the tip than in any other species.” No such peculiarity in the shape of the telson is apparent in our 
specimen. 
The individual from station 4166 is 62 mm. long, of which 16 mm. belong to the rostrum (in front 
of the supraocular spines), but the rostrum is damaged at the tip. The specimens from station 4005 
are all smaller than this one, the smallest possessing a total length of 34 mm. Wood-Mason gives 
75 mm. from tip of the rostrum to end of telson. 
The label of the set from station 4005 gives the color as “scarlet vermilion;” in the specimen 
from station 4166 the color is still preserved, and is of a brilliant scarlet. All our specimens seem to 
be males, since in none of them are incubatory lamellae visible. 
Stations: 4005, 577-480 fathoms, vicinity of Kauai Island, 4 males; 4166, 293-800 fathoms, vicinity 
of Modu Manu or Bird Island, 1 male. 
Distribution. — Bay of Bengal, 16° 55 / 41" N., 83° 21 / 18" E., 840 fathoms (Wood-Mason). 
The above localities extend considerably the range of this species. 
14. Gnathophausia longispina G. 0. Sars. 
Gnathophausia longispina G. O. Sars, Bep. Voy. Challenger, 13, 46 pi., 7 f., 1-5, 1885. 
An examination of the rich material of this species collected by the Albatross shows that there is 
quite a variability in the development of the different spines of the carapace. The length of the 
rostrum and dorsal spine varies considerably; generally they are comparatively longer in young 
specimens. The branchiostegal spines in older specimens are not quite so strong and are directed 
obliquely forward, and the outer spine of the antennal scale is not so excessively developed.
