REVIEW OF THE MARINE CRUSTACEA OF LABRADOR. 
By SIDNEY I. SMITH. 
Almost the only source of information in regard to the crustacean 
fauna of the coast of Labrador has been Professor Packard’s “A list 
of the animals dredged near Caribou island, southern Labrador, during 
July and August, 1860” (Canadian Naturalist and Geologist, viii, pp. 
401-429 (1-29), December, 1863), and his “‘ View of the recent inver- 
tebrate fauna of Labrador” (Memoirs Boston Soc. Nat. Hist., i, pp. 
262-303, pll. 7, 8, 1867). At the time these papers were written it was 
exceedingly difficult in this country to identify the marine invertebrata 
of our northern coast, and the lists of crustacea given by Professor 
Packard were necessarily very imperfect ; the species described as new 
had apparently all been previously described by European authors ; the 
identifications were in many cases incorrect; and in several cases the 
same species appears under different names. Of this last class of errors 
several are due to the fact that some of the Amphipoda were identi- 
fied for Professor Packard by Dr. Axel Boeck, others were deter- 
_ mined by comparison with Arctic specimens from Dr. Liitken, of 
Copenhagen, while still others were determined from the published 
descriptions by American and European authors. In the following 
pages I have attempted not only to revise Professor Packard’s 
lists, but also to give a complete catalogue of all the species known 
from the Labrador coast. In determining Professor Packard’s species 
I have been greatly aided by a set of his specimens collected in 1864 
and labeled by him for the Museum of Yale College. This colleetion 
has enabled me to determine many of the species enumerated by Pro- 
fessor Packard which were otherwise indeterminable, and also to add 
a number of species overlooked or incorrectly determined by him. The 
nomenclature adopted for the Amphipoda is mainly that of Boeck 
(Skandinaviske og Arktiske Amphipoder), and for the Isopoda that of 
Harger (Marine Isopoda of New England, Report U.S. Fish Com., part 
iv, for 1878). Ihave not attempted to give synonymy except to show 
to what species the names in Professor Packard’s lists are referred, but 
I have intended to insert references to all the names of marine species 
in each of his lists. For the distribution of the species along the Lab- 
rador coast I have thought it sufficient to indicate only whether the 
_ Species has been found on the Gulf or Atlantic coast, or on both coasts, 
and for this purpose I arbitrarily divide the coast at 51° 50/ north lati- 
tude, a little south of Chateau and Temple Bays, regarding all south 
and west of this point as Gulf coast and all north of it as Atlantic 
coast. When not otherwise indicated the regions from which I have 
examined specimens are followed by a mark of affirmation (!),
