64 PROCEEDINGS OF THE CALIFORNIA 
Numerous Decapoda from Panama and Nicaragua have recently been 
described by S. I. Smith, and others by Hale Streets, yet the series of new 
forms given by them must be considered only as a sample of the riches of 
that region. 
Even in and around San Francisco Bay we have found several new species 
of Tetradecapoda, and probably a systematic dredging would bring to light 
many more. 
Very little dredging has been done along the coast, and that little has been 
confined te comparatively shallow depths. 
The fresh-water streams and lakes of California, as well as those of Mexico, 
have yet to yield their quota of species for some future check list. 
‘The Entomostraca and Cirripedia as yet describe! are very few, and these 
departments offer a large and inviting field to the naturalist. 
It is my intention, from time time, to furnish the Academy with additional 
notes of the species already known, as well as descriptions of such new 
species as may be sent to us. 
Some few of the new species included in this list may, without doubt, prove 
to have been already described, but I feel assured that this will only be the 
case with Alaska forms, some of which may probably range throughout the 
Arctic Seas, inhabiting both North Pacific and North Atlantic. 
The names of the naturalists who have described species are given in full 
throughout this list, with the exception of Stimpson, which is abbreviated 
to St. 
The species at present in the collection of the Academy are denoted thus *
