204 A HISTORY OF RECENT CRUSTACEA 
Family Hectarthropide. 
As this is the only family, its characters are those of 
the legion. The four genera assigned to it were instituted 
at the same time as the family and legion. 
Proclétes, Spence Bate, 1888, meaning ‘ Challenger,

is described as Procletes biangulatus, the other Procletes El- 
lioti, which has a smoother carapace, a shorter flagellum, 
and a longer telson, being described, it seems, only from a 
drawing, not from the original specimen taken by the late 
Sir Walter Elliot, years ago, off the coast of Coromandel. 
Icotépus and Hectarthropus* proclaim their adhesion to 
the family by the meanings of the names, the former 
signifying ‘with similar feet,’ the latter ‘ with six-jointed 
feet... The fourth genus which Spence Bate establishes in 
this family, Hretmocdris, ‘the oar-shrimp,’ in allusion to 
the provision of exopods or swimming-branches, is pre- 
sumably founded on immature specimens, since it is ob- 
served that ‘the first three pairs of appendages in this 
genus, the eyes and two pairs of antennez, are attached to 
a portion of the cephalon projected in front of the carapace, 
which still retains the embryonic ocellus.’ The animals 
have a very striking appearance from the unusual and
