collectors, or later by Dr. W. H. Jones, U. S. Navy, who, with Dr. T. H. Streets, 
was surgeon and naturalist on the U. S. S. Portsmouth during the survey of the 
North Pacific Ocean in 1873-74. 
Through the courtesy of Mr. Witmer Stone, the writer has made an examination 
of all of Randall’s types of Hawaiian crabs and shrimps extant in the museum of the 
Philadelphia Academy of Natural Sciences. Some of these have been noted by 
Kingsley, Sharp, and Ortmann, but the validity of Penseus marginatus Randall is 
here established for the first time. 
The Hawaiian fauna is almost entirely Indo-Pacific, the islands forming the 
northeastern, as the Indian Ocean is the southwestern limit, for the majority of the 
species. This is true of the shore and shallow water forms a and in a lesser degree 
of the abyssal forms, of which many are cosmopolitan and have been described by 
Smith, Bate, A. Milne Edwards, or Alcock, from the depths of the Atlantic, Pacific, 
or Indian oceans. 6 This circumstance of wide horizontal distribution of deep-water 
species has recently been emphasized by Ortmann in reporting on the Schizopoda.” c 
Besides 76 of the 80 species here described as new, few species are restricted 
to the Hawaiian Islands, and such apparent restriction may be due to incomplete 
knowledge. Very little affinity to the fauna of the American continent is shown. 
Micro panope sexlobata, a new species, forms a marked exception, as the genus is 
tropical American and the Hawaiian species is akin to M. truncatifrons Rathbun of 
the West Indies. 
The figures of Cyrtomaia smithi were drawn by the late Dr. J. C. McConnell; 
the other drawings of Brachyura, as well as all the colored plates, are the work of 
Mr. A. H. Baldwin; Miss E. G. Mitchell made the pen and ink drawings of most 
of the Macrura. The photographs were taken by Mr. Clarence Dodge, excepting 
Plates I and II, which are the gift of Mr. H. W. Henshaw.
