ZOOLOGY. AKTHROPODA. 151 



One specimen (dredged) which agrees well with Gibbes' de- 

 scription (Proc. Aiuer. Assoc, 1850, p. 196), and seems to indi- 

 cate that the species is distinct from Alph&us minus, with which 

 it is united by Kingsley. The specimen is larger than any of 

 the individuals of A. minus, and is also differently colored, 

 although appearing identical in alcohol. 



Falsemoiiella tenuipes, Buna. 



Several specimens dredged off Shelly Bay, which agree per- 

 fectly with the species described by Dana from the Sooloo Sea 

 (U. S. Exploring Expedition, Crustacea, p. 582). The remark- 

 able distribution here indicated induced me to make a very 

 careful examination of the Bermudian species, which has left 

 no doubt in my mind as to the identity of the forms from the 

 antipodal regions of the earth's surface. The only other 

 known species of Palfomonella, P. orientalis (Dana), is likewise 

 an inhabitant of the Sooloo Sea (Dana, op. cit. ; Spence Bate, 

 Challenger Reports, Zoology, XXIV, p. 786). 



Falsmon affinis, Milne-Edwards. 



Numerous specimens from shallow water. Castle Harbor. 

 All are exactly like one another except in the number of teeth 

 on the beak, which may be 8 above and 4 below, or in rela- 

 tions of 8-3, 7-3, 9-3, and 9-4. This character is manifestly 

 a very variable one, and, therefore, of little or no value from 

 a classificatory point of view. The specimens agree well with 

 the descriptions and figures of ^4. affinis, although that 

 species has hitherto been recorded, as far as I am aware, only 

 from the Pacific (obtained by Dana off New Zealand). The 

 species is near to the Eurafrican P. squilla, but yet sufficiently 

 distinct to permit of ready recognition as only an allied form. 



It is remarkable, in view of the distribution and the num- 

 ber of specimens that we obtained of this species, and the 

 position of the island group, that we should have failed to ob- 

 tain any individuals of the common form of the eastern 

 United States, Palasmon vulgai-is. Whether the species is
