196 THE SCHIZOPODA. 
first pair of legs is lost I refer this species to Hemisiriella, because the preserved 
second joint of these legs is thicker than that of second pair, because the cara- 
pace is extremely short, etc. 
ANCHIALINA Norman (1906). 
No specimen of this very characteristic genus was taken by Dr. Agassiz 
in 1904-1905, but three species were secured by the ‘‘ Albatross” in 1900 at — 
Butaritari, Gilbert Islands, and one of these species is new to science. The 
genus has been revised in my ‘‘Siboga”’ paper. 
15. Anchialina typica (Kroyer). 
1861. Anchialus typicus Kr6yeEr, Nat. Tidsskr., 3 R., 1, p. 53, tab. 2, fig. 7, a-l. 
1910. Anchialina typica H. J. HANSEN, Siboga-Exp., 37, p. 52, pl. 7, figs. 2a-2k. 
Butaritari, Gilbert Islands. Jan. 6, 1900. Lagoon. Surface. Light. 7 specimens. ‘‘Albatross.’’ 
Remarks.—— The specimens are all adult males. They are somewhat 
small, measuring about 5.5mm. in length, but they agree closely with smaller 
“Siboga” specimens in all particulars. The exopod of the third pair of 
pleopods has not four but only three long, slender processes, each with a 
terminal seta; these processes are found on the fifth, sixth, and seventh joint 
counted from the distal end, while in the ‘‘Siboga”’ specimen figured (fig. 
2i) such processes are found on the fifth to the eighth joint; in small ‘‘Si- 
boga”’ specimens such processes are wanting on the eighth joint or even on the 
seventh and the eighth joints, as already stated in my paper. 
Distribution.— A. typica has a very wide distribution, and it may be suffi- 
cient to give an abstract of the statements in the ‘“‘Siboga”’ paper. The species 
is known from tropical Atlantic (Kréyer), the West Indies, the Gulf of Siam, — 
several places in the Indian Archipelago, and probably the Hawaiian Islands. 
16. Anchialina grossa H. J. Hansen. 
1910. Anchialina grossa H. J. HANSEN, Siboga-Exp., 37, p. 54, pl. 7, figs. 3a-3n; pl. 8, figs. la-1d. 
Butaritari, Gilbert Islands. Jan. 6, 1900. Lagoon. Surface. Light. 1 specimen. “Albatross.” 
Remarks.— The specimen is an immature female. In the shape of the 
frontal plate with rostrum, the size of the eyes and the shape of the exopod of 
the uropods it agrees perfectly with females of A. grossa from the Indian Archi- 
pelago. 
Distribution.— A. grossa was taken at several places in the Indian Archi- 
pelago, and besides it is known from the Gulf of Siam and the Bay of Bengal 
(the author).
