THE GALATHEIDEA (CRUSTACEA ANOMURA) 



OF THE ALLAN HANCOCK ATLANTIC EXPEDITION 



WITH A REVIEW OF THE PORCELLANIDAE 



OF THE WESTERN NORTH ATLANTIC 



By Janet Haig 



INTRODUCTION 



During its cruise into Caribbean waters in April, 1939, the Velero 

 III under the command of Captain Allan Hancock amassed a large 

 collection of anomuran Crustacea. The Galatheidea, which are the 

 subject of the present report, are represented in this collection by three 

 species of the family Galatheidae and 23 of the family Porcellanidae. 

 All of them were taken in the littoral or at depths not exceeding 41 

 fathoms. It is interesting to compare the Galatheidea collected in the 

 Caribbean by the Atlantis in the same and preceding year, from 150 to 

 over 1600 fathoms (Chace, 1942). From that expedition the Chiro- 

 stylidae and Galatheidae were represented by 48 species, and the Por- 

 cellanidae by a single deep-water form. 



In addition to the Velero III material, a few specimens from south- 

 ern Florida are included in this report. They were collected by L. A. 

 Burr>' in 1945, J. S. Garth in 1946, and L. O. Miles in 1949-50, and 

 are now housed in the Hancock Foundation. All but the 1950 collecting 

 stations were assigned Hancock station numbers. 



Also included is a porcellanid collected in Santa Marta, Colombia, 

 by I. Vigeland on his return to Europe from Chile where he took part in 

 the Lund University Chile Expedition of 1948-49. The specimen has 

 been returned along with the other Anomura from this expedition, all 

 of which were examined by the writer. 



For the geographical account and station records of the Allan 

 Hancock Atlantic Expedition of 1939, the reader is referred to Garth
