Pandalopsis is a MS. name of A. Mihie Edwards's^ adopted by Bate. This 

 genus is distinguished from Pandalus by the greatly elongated llagella of 

 the antennules, and by the laminate expansions of the merus of the third 

 maxillipeds and of the ischium of the first pair of legs. The third maxilli- 

 ped has no exopod. The epipods of the legs are rudimentaryj as in Pandalus 

 and Ileterocarpus, The branchial formula is the same as for Pandalus and 

 HeierocarpuSy viz. : —

Five specimens (two of them ovigerous females), without a label, agree 

 pretty well with Kingsley's description oi A. panamensis. There is a small
