Series II. 



Pp.eparkd by Eiciiard Rathbun. 



The species enumerated in the present list were collected by the TJ. 

 S. Fish Commission, mainly during the past four years, and represent a 

 portion of the dui)licate material resulting from their sea-coast explora- 

 tions, and now available for distribution. Several of the species in- 

 cluded in these duplicate sets are recent additions to science, obtained 

 by the U. S. Fish Commission steamer Fish Hawli, from the inner edge 

 of the Gulf Stream Slope, south of Martha's Vineyard, during the sum- 

 mers of 1880 and 1881. This region, which was first explored in 1880, 

 has proved to be the richest dredging ground yet discovered upon our 

 coast, both as regards variety of life and abundance of specimens. 



Nearly all the species enumerated are included in each set, but of a 

 few species only enough duplicates were secured to sui)ply a i^ortion of 

 the sets. In the printed list to accompany each set sent out, the species 

 omitted from that set will be erased. Except where otherwise indicated, 

 the specimens are all preserved in alcohol. The sets will number about 

 one hundred. The Crustacea have been identified, for the most part, by 

 Prof. S. I. Smith, and most of the other species by Prof. A. E. Verrill. 

 The names are mainly those used in the Preliminary Check-list of the 

 Marine Invertebrata of the Atlantic Coast, by A. E. Verrill, edition of 

 1879. A considerable number of species that have since been described 

 are, however, here included.
