one from Honolulu but are very much darker in color. A 

 crescent-shaped, black patch on either side of the median ridge 

 of the telson is distinct in these specimens. 



The largest specimen in the Bishop Museum collection, a 

 male from Honolulu, measures 247 mm. from the tip of the 

 rostral spine to the posterior border of the telson. The largest 

 of the four specimens from Taliiti. a female, is 218 mm. in 

 length. 



The Bishop Museum collection includes specimens irom Tahiti 

 and Honolulu. 



The species is widely distrilmted throug-hout the Indo-Pacific
