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 onlv 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 to 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 described 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 *.
