The Stomatopoda are, without doubt, less abundant than some 
other well-known groups of Crustacea; their great agility when 
moving freely in the water and their powers of concealment, 
rendering their capture a difficult task, may, however, partly 
explain why a larger number of Squillidae have not been described. 
Up to the present time the number of species reported is 
probably below one hundred and fifty and, on consulting the liter- 
ature, one finds that not a few of this number have been described 
from one or two specimens. 
Although the collection of Stomatopoda in the Bishop Museum 
is at present not large, yet a considerable degree of interest is 
attached to it from a distributional point of view. 
The collection comprises fifty-three specimens, grouped under 
six genera and nine species, one of which is new. Of the fifty- 
three specimens ten are recorded from Guam, four from Tahiti, 
and two from the Marquesas, the other thirty-seven being from 
Hawai. 
Representatives from the Hawatian waters are listed under 
six genera and eight species. [If one may infer from the frequency 
with which they are taken, three of the species of Squillidae found 
in Hawaiian waters exist in much greater number on the reefs 
and in the shallow water about the islands than do the other five 
species. 
Pseudosquilla ciliata Miers, a widely distributed species, is 
very common on the reefs about Oahu. Another species of the 
same genus, Pseudosquilla oculata (Brullé), previously reported 
from the Canaries, Madeira, Cape Verde Islands, Mauritius, 
Chagos, Samoa, and the China Sea, has frequently been taken 
from the dead coral blocks on Waikiki reef, Honolulu. A third 
species, Squilla oratoria de Haan, more or less common in Chinese 
and Japanese waters, has several times been found in the Hono- 
lulu fish market during the present year, but the writer has never 
taken the species from the reefs about Oahu and is unable to say 
where the fishermen obtain it. 
Other species of Squillidae taken from Hawaiian waters are, 
for the most part, represented in the Bishop Museum collection by 
single specimens.
