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). 



ISOl. Aiichialus lypiciis Kroyer, Nat. Tidsslvr., 3 R., 1, p. 53, tab. 2, fig. 7, a-1. 

 1910. Aiichialina typica H. J. Hansen, Siboga-Exp., 37, p. 52, pi. 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 5.5 mm. in length, but they agree closely with smaller 

 "Siboga" specimens in all particulars. The exopod of the third pair of 

 pleopods has not iour 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 (Kroj^er), the West Indies, the Gulf of Siam, 

 several places in the Indian .li'chipelago, and probably the Hawaiian Islands. 



16. Anchialina grossa H. J. Hansen. 



1910. Anchiidina grossa H. J. Hansen, Siboga-Exp., 37, p. 54, pi. 7, figs. 3a-3n; pi. S, figs. la-Id. 

 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 Ai-chi- 

 pelago. 



Distrihulion. — A. grossa was taken at several places in the Indian Archi- 

 pelago, and l)esides it is known from the Gulf of Siam and the Bay of Bengal 

 (the author).
