Ai\U OTHER CRUSTACEA'' 
i he crustacean collection, though not large, contains several novel- 
ties ; a new species, Thalaimta rooscvclfi: and two new subspecies 
CaUuuudca lacvicaiida occidcufalis and Crangon luraudicnsis cUppcr- 
foiii. A West Indian s])ecies, Calliatwssa hariinevcn. earlier reported 
by blult ( Arkiv Zool., ^•oI. 30A, No. 5, 7. text figs. 1-4. pi. 1. figs. 
ta, tl), 1938) from the Galajiagos, was found at Socorro Island. 
Brachycarpus bniiigiticulafus, another West Indian ,s])ecies, originally 
described from Bermuda and well known in the -Mediterranean, with 
also a single record from the Red Sea. rather sur|)ri,siiigly turned up 
III the Chiiperton Island material, a first truly Pacific record, for this 
species. An Ogyridcs. the first representatir'e of the genus from the 
west coast of -America which was taken at lAinta Gorda, as well as 
a ( laiigoii from Socorro, a |)ossible new variety of Crangon para- 
crnutiis from Ch]jperton, and several siiecies of PcfrolisHies, ha\-e not 
been described for want of adequate material of each of them. Other- 
wise, there is a small residuum of very fragmentarv specimens. 
juveniles, and larval forms, not satisfactorily determinable, that are 
not included in tliis re]:)ort. 
In this list we are able to enumerate approximately too different 
decapods, including 4 species of porcellanid or flat crabs : in addition, 
there is 1 leptostracan, a barnacle, and 8 species of co])ei)ods, making 
a total of no different kinds of Crustacea. The greatest number of 
si-ecics listed for any one station was 42 from Old Prow'dence : next 
in order. 17 from Sulivan Bay, James Island, Galapagos. 
^ Of the new forms described in this ]3aper, two were collected at 
Chpiierton Island, where, so far as 1 have been able to ascertain, 
little or no marine carcmological collecting has ever been done before. 
This coral atoll, which is unique in American waters, supports a 
remarkably interesting marine fauna, inasmuch as 7 of the 18 spe- 
cifically identified species have strong Indo- Pacific ties, and i Bracliv- 
carpiis biiingiticidatiis. a less strong tie. Indeed, four of those seven 
species are identical with species known from Hawaii and be}-ond. 
The aniphipods and isopods will ajipear as separate reports 
Shoemaker and J. O. -Maloney, respectively, of the Division of 
brates, U. S. Xational Aluseum.
