PRELIMINARY REPORT ON THE BRACHYURA AND ANOMURA 
DREDGED IN DEEP WATER OFF THE SOUTH COAST OF NEW 
ENGLAND BY THE UNITED STATES FISH COMMISSION EIN 1880, 
1881, AND 1882.

By SIDNEY I. SMITH. 
This report is intended to be supplementary to my preliminary notice 
of the crustacea dredged in the same region in 1880 (these Proceedings, 
iii, pp. 413-452), and to include all the species of Brachyura and Anomura 
obtained off Martha’s Vineyard at depths greater than 50 fathoms. 
The crustacea dredged off the mouth of Chesapeake Bay in 1880, and 
off the capes of the Delaware in 1881, will be the subject of a separate 
report, but the specimens from these dredgings are included in the fol- 
lowing lists of specimens examined as far as the species to which they 
belong are contained in the present report. 
A few of the species described as new in the preliminary notice above 
referred to were almost simultaneously described by A. Milne-Edwards 
in one of the reports of the Blake dredgings, under the supervision of 
Alexander Agassiz, in 1877, 1878, 1879 (Bull. Mus. Comp. Zool. Cam- 
bridge, vol. viii, No. 1, December 29, 1880), of which I had no knowledge 
whatever until after my paper was printed (January, 1881), and which was 
- not published until after my last proof had been returned to the Public 
Printer (December 24, 1880). I have had much difficulty in identifying 
Milne-Edwards’s species, but have adopted his names wherever it was 
possible to recognize his species. In determining some of these spe- 
cies I have been greatly aided by the kindness of Prof. Walter Faxon, 
who has sent me for examination some of the type specimens in the 
Museum of Comparative Zoology.* 
The last season’s dredging off Martha’s Vineyard reveals the total, 
or almost total, disappearance of several of the larger species of crus- 
tacea which were exceedingly abundant in the same region in 1880 and 
1881. The most remarkable cases are those of Huprognatha rastellifera, 
Collodes robustus, Catapagurus Sharreri, Munida Caribea? Smith, and 
*While the manuscript of this report was in the hands of the printer, the follow- 
ing work of Milne-Edwards was received: Recueil de figures de Crustacés nouveaux 
ou peu connus. lére livraison. April, 1883. A considerable number of Milne-Ed- 
wa. 's’ new species are provisionally figured in this work, but it does not seem to 
make ai.7 changes in the proofs of the following pages necessary, except under Anop- 
lonotus politus, which was doubtfully referred to Elasmonotus in the original manu- 
script, but for which the new generic name has been inserted in the proof.—May 29,
