BRACHYURA AND MACRURA OF HAWAIIAN ISLANDS. 
839 
Napili Harbor, Maui, station 3881, 2 females (1 ovigerous). Hawaiian Islands, W. H. Pease, 
North Pacific Exploring Expedition, 1 female, type of G. subquadratus Stimpson. Hawaiian Islands, 
A. Garrett, 1 female in Museum of Comparative Zoology. 
“Under stones below half-tide mark on the ocean shore at Hilo ” (Stimpson, unpublished MS.) 
A smaller form than typical G. strigosus, a female bearing eggs measuring only 24.2 mm. long; 
also wider and more quadrate; front less advanced; fingers gaping in their basal half; ambulatory legs 
much longer, 2J times as long as carapace, meropodites narrowing more distinctly at the distal end, 
propodites markedly elongate; abdomen of mature female very wide, almost concealing the coxse of 
the ambulatory legs; abdomen of male broader, equilaterally triangular from the middle of the third 
segment to the tip. 
The type of Dana’s G. longitarsis is also in the National Museum; it is a male smaller than the 
females. I can not see that it differs essentially from the type of G. subquadratus. 
Dimensions. — Length of larger female from Napili 24.6 mm., greatest width 28.2, width at exorbital 
angles 23.7, at epibranchial tooth 25.8, width of front below 11.4 mm.
