Vol. III., p. 18. Habitat: Mediterranean 

 and coasts of Chili ; not previously recorded 

 from Falklands. 



Of the seven species of Crustacea in this collection 

 of common shore fauna, one is common to the northern 

 and southern hemispheres {Orchestia chilensis), two are 

 distributed over the temperate portion of the southern 

 hemisphere, and four are peculiar to the neighbourhood of 

 the Falklands. 



Paralomis. The genus occurs north and south of the 

 tropics but not within the tropics; of 3 species, 2 occur in 

 moderately deep to deep water, 310-600 fath.; the third, 

 P. verrucosus, appears to be a shallow-water form. 



Halicarcinus. The genus appears to be widely and 

 universally distributed over the southern portions of the 

 three great continents in the southern hemisphere. 



Xantho. Genus cosmopolitan, and fossil. 



Eupagurus. The genus is distributed in north and 

 south temperate regions as well as the tropics, but the 

 species of this genus appear to be very limited in their 

 distribution. The depths vary from o to 700 fathoms. 



Edotia. The distribution of this genus appears to be 

 somewhat doubtful. A species, E. bicuspida, occurs in 

 the Arctic seas. I have been unable to ascertain if the 

 genus is represented in the tropics. 



Sphceronia. The genus appears to be almost univer- 

 sally distributed over the temperate and tropical areas, but 

 the species appear to have a very limited distribution. 



Orchestia. The genus appears to be cosmopolitan in 

 temperate and tropical littoral waters ; the species of this 

 genus, like those of other genera in this collection, are 

 limited in their distribution. 



Regarding the seven genera represented in this collec- 

 tion : three {^Eupagurus, Sphceroma, and Orchestia) are
