BARBADOS-ANTIGUA EXPEDITION 73 
University collection in some minor details, but evidently iden- 
tical generically. It is truly bizarre in appearance, being much 
flattened and having the carapace produced laterally by the 
great extension of its edges and terminating in rows of stout 
curved spines. The eyes are very far apart on the dorsal sur- 
face, sunken in pits and with extremely short eye-stalks. The 
antenne are astonishingly modified, that which probably repre- 
sents the squamous portion being produced into a great flat- 
tened triangular shield, forming what appears an be an antero- 
lateral extension of the carapace with which it is strictly con- 
tinuous. The rostrum forms a very low triangle with the broad 
base transverse to the carapace between the antenne. The body 
is mottled dull brownish and yellowish and covered with smooth 
dome-like tubercles, each of which is surrounded by a circle of 
small stiff hairs. There are no chele, all of the legs ending in 
strong and curved hooks. The specimen is a female and has a 
total length of seven and one-half inches and a breadth of four 
inches. 
The Anomura are represented by several species of hermit- 
erabs. The smaller and more abundant of these are known as 
‘‘soldier-erabs’’ from their habit of proceeding seaward in large 
numbers at certain times. A very small species inhabiting the 
shell of a Dentalium differs from nearly all the others of the 
group in being bilaterally symmetrical instead of twisted to fit 
the spiral coils of the shell which it inhabits. The Dentalium 
itself is straight, with no twist whatever, and the hermit has 
adapted its form to this style of habitation. Its chele form a 
perfect operculum, orbicular in ‘form to fit the aperture of the 
shell. The largest hermit crab that I have ever seen was Hupa- 
gurus granulatus, collected near Pelican Island, where it inhabits 
a large gastropod shell, probably a Strombus. This crab was 
thirteen and one-half inches in length, a monster of its kind. 
Brachyura.—Big land-crabs were abundant and excellent eat- 
ing, although we could afford but one mess of these, the speci- 
mens being too valuable in collections to warrant us in using them 
often in the commissary department. Besides there were sev- 
eral in our party who did not take kindly to strange sea-food. 
For my part, I am truly sorry for those conservative people who 
have to be brought up upon an article of diet before they can
