104 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 120 
Palau: Sta. 333, Kapingamarangi, daly 20, 1954, C. Hand, 1 juv. 
MEASUREMENTS.—Males, 14-24 mm.; sferled 11-22 mm.; ovig. 
females, 14, 15 mm.; juv. 10 mm. 
ReMarks.—The male pleopod, which shows resemblances to that 
of T. quadridens, does not appear to have been figured or described. 
It is short, stout, gently curved, with a swollen truncate tip. Sub- 
terminal armature on outer side consists of a scattered row of elongate 
bristles followed distally by a tightly packed clump of medium-sized 
and long bristles. Inner side bears distally four spinules followed by 
a patch of short curved bristles. 
Past authors have disagreed on the status to be given to the Red 
Sea forms and to the remainder. In some cases (e.g., Edmondson, 
1954), subspecific ranks are given with the present form, Thalamatoides 
tridens typica. The most recent author (Crosnier, 1962), while dis- 
regarding a varietal heading to the more widely spread forms, refers 
to those from the Red Sea as variety spinigera. 
DisTRIBUTION.—Madagascar, Guam, Samoa, and Fiji.
