Inachine, hitherto represented only by types from Eastern 
America.’ Among those types the nearest to Platymaia 
is supposed to be Huprognitha, Stimpson, 1870. In re- 
gard to Huwprognatha rastellifera, Professor 8. I. Smith 
says: ‘This is apparently by far the most abundant of all 
the Brachyura along our whole eastern coast south of 
Cape Cod—in the belt from 50 to 200 fathoms depth. 
In the U.S. Fish Commission dredgings off Martha’s 
Vineyard, many thousands of specimens were often taken 
at a single haul of the trawl.’ 
Family 2.—Maiide. 
The eyes are retractile within the orbits, which are 
distinctly defined, but often more or less incomplete below 
or marked with open fissures in their upper and lower 
margins. The basal joint of the second antenne is always 
more or less enlarged. The family includes about thirty 
genera, three of which are known in British localities. 
Maa, Lamarck, 1801, is a genus well known rather to 
the south than the north of Great Britain in the species 
Maia squinado (Herbst). It is a large, eatable, and, in the 
south-west of England, an extremely abundant species. 
Its great inflated carapace, covered with prickles and fur, 
gives it a ready place in the memory when once it has been 
noticed. A pretty little amphipod, called [scea Montaqut, 
Milne-Edwards, with the sixth joint of its legs much 
widened, seems to have been specially adapted for ranging 
about this hirsute and prickly crab, the only place in which 
it is found. The convenience of the residence may be in- 
ferred from the fact, previously noticed, that from time to 
time a score of other species of Amphipoda find it their 
interest to occupy the same station. The crab, according 
to Herbst, is known as Squinado in Provence. In Corn- 
wall it is called the Corwich, and Bell was told that in 
those parts several dozens could be had for sixpence. But 
even this does not give so ample an idea of its abundance 
as is conveyed by Olivi in his ‘ Adriatic Zoology’ of a 
hundred years ago. He declares that in summer the crabs
