PACIFIC SCIENCE, Vol. XXII, July 1968 
collection, Vervoort (in litt.) informed us that 
these specimens were identical. Since a descrip- 
tion of the female of L. gigas has never been 
published we have presented a diagnosis of the 
female here. 
Lophothrix similis Wolfenden, 1911 
remarks: Since its description by Wolfenden 
(1911), Lophothrix similis has not been re- 
ported again. Wolfenden’s specimen was found 
in the South Atlantic, and therefore the females 
reported here constitute the first record for the 
Pacific Ocean. Our specimens range in size 
between 7.08 and 7.41 mm, which is larger than 
that reported by Wolfenden (5.5 mm). 
It should be added here that the posterior 
lateral margin of the fifth thoracic segment is 
rounded and protruded, as in L. frontalis. No 
mention is made of this in the original descrip- 
tion.
