Edmondson—Stomatopoda in the Bishop Museum 289 
The collection of Squillidae in the Bishop Museum consists of 
twenty-one specimens of this well-known and widely distributed 
species. Of this number seven, three males and four females, 
were taken by Alvin Seale at Guam in 1900, one, a male from 
the Marquesas by the same collector in 1902, five, three females 
and two males, from the reef near Koko Head, Oahu, by the 
writer in 1920, and four, two males and two females, from the 
reef at Waikiki, Honolulu, by J. M. Ostergaard and the writer 
in 1921. Four other specimens, two males and two females, 
included in the collection are without data but probably are Ha- 
waiian. 
The specimens are, in most details, quite typical. The basal 
prolongation of the uropeod in the specimens from Guam, the 
Marquesas, and Oahu extends slightly beyond the tip of the 
endopodite but does not reach the distal extremity of the exo- 
podite, as is indicated in the description of the type specimen by 
Miers. 
All the Bishop Museum specimens agree with the descrip- 
tion by Brooks of a specimen from Honolulu, in having the inner 
spine of the prolongation of the uropod longer than the outer. 
Brooks states, however, that in the Honolulu specimen the distal 
segment of the exopodite of the uropod is about as long as the 
proximal segment. But none of the Pacific forms in the Bishop 
Museum agree with his description in this feature, the distal seg- 
ment of the exopodite being slightly less than five-eighths as 
long as the proximal one. In this respect the specimens corres- 
pond more closely with those taken in the region of Porto Rico, 
according to Bigelow’s description.® 
The presence of postero-lateral spines on the fourth abdo- 
minal segment is apparently a variable characteristic of the species 
even in the same locality. Two of the nine specimens from 
Oahu show such spines, as do two of the seven specimens from 
Guam. All bear postero-lateral spines on the fifth abdominal 
segment.
