372 "ENDEAVOUR" SCIENTIFIC RESULTS. 



Tribe CARIDES. 

 Family CAMPYLONOTID.E. 



Though the genus upon which this family is based 

 was first described by Bate, 54 it was never well under- 

 stood or properly appreciated until studied by Sollaud, 55 

 who instituted the present family in 1910. He has given 

 a useful key to the families of the subtribe Hoplophorida, 

 erected by Borradatte 56 in 1907 of which the Campylono- 

 tidae must now be recognized as one as well as a key 

 to the known species of the typical and only genus 

 included in the family. These keys have been introduced 

 below; the new Campylonotid taken by the "Endeavour" 

 has been added to the key of species.
