 6 plates and chart. 

 The collection contains 15 species. Four- 

 teen of these are marine species and are new 

 to science. The other, a land species, is 

 well known. Of the 14 marine species, 8 are 

 free-living and 1 is parasitic on fishes. These 

 9 species belong to known genera. The re- 

 maining 5 species are peculiar forms of the sub- 

 family Bopyrinai, and occur in the branchial 

 cavities of deep sea decapod crustaceans. 

 The chart shows the route of the Albatrosx.

 pp. 116-122. 

 This discussion is germane to a monograph 

 on Eskimo lamps, which will be published 

 later. The author points out that the Eski- 

 mo could not live without lamps, which they 

 have possessed from time inuuemorial. The 

 fact that their lamps originated from beach 

 stones with natural concavities, and that they 

 range from this simple form to highly finished 

 examples of stone and pottery, shows that the

size and form of the lamps bear so distinct a 

 relation to the isothermal lines and zone of 

 winter darkness, that it is possible by com- 

 parison to assign the geographical position of 

 any specimen.
