EXPLANATIONS AND ACKNOWLEDGEMENTS 



In the following account, short descriptions are given for most of the 

 species, except for new or poorly known forms which are described in 

 some detail. Some general terms used in the descriptions and keys 

 are illustrated in Plate 1. Synonymies are complete unless otherwise 

 stated ; for the most part, synonymies and accounts of the species are 

 restricted to adults only. Total length is measured from the apex of 

 the rostral plate to the tips of the submedian spines of the telson. Other 

 length measurements are made along the midline, and width measure- 

 ments are made at the widest point. The count for the teeth of the rap- 

 torial dactylus always includes the terminal tooth. An abdominal spine 

 formula of submedian, 6; intermediate, 5-6; lateral, 5-6; marginal, 

 1-5 ; indicates that the submedian carinae terminate in spines on the 

 sixth abdominal somite only, the intermediate carinae terminate in
