The Decapoda collected by the " Huxley " from the North 

 Side of the Bay of Biscay in August, 1906. 



By 

 Stanley Kemp, B.A. 



The collection of Decapoda made by the Hmdey during her short 

 cruise on the north side of the Bay of Biscay is an extensive one ; it 

 comprises no less than forty-nine species — a number which speaks 

 well for the efficiency of the gear employed. 



Although, as might' be expected, the majority of the species obtained 

 are well-known members of the N.E. Atlantic fauna, the material 

 presents many points of interest. Five species not hitherto known 

 to extend south of the British Isles were found by the Huxley, and 

 in several cases important additions have been made to our knowledge 

 ■of the bathymetric range. 



A specimen which has been tentatively referred to Periclimenes 

 Komi (Lo Bianco) is of the greatest possible interest, for no deep- 

 water representative of the family Paltemonidse was hitherto known 

 from the N.E. Atlantic. Unfortunately, the species is represented only 

 by a fragment of a single individual ; this is particularly irritating, 

 for the collection, as a whole, is in a remarkably good state of pre- 

 servation. 



No close comparison can be made between the species in the 

 present collection and those found by the Caudan in 1895, for the 

 latter expedition worked considerably to the south of the area investi- 

 gated by the Huxhy ; nevertheless, two species, Sjjongicola Kochleri 

 and Uroptychus Bouvicri, which were first described from material 

 obtained by the Caudan, have again been found. Until now, both 

 these forms were known only from the type specimens. 



My thanks are due to Dr. E. J. Allen for the opportunity of 

 -examining this interesting collection.
