Thalamita edwardsi Borradaile, Proc. Zool. Soc. London, 1900, 579; Fauna and Geog. Maidive and 
Laccadive Islands, I, 1902, 202. 
In the Hawaiian collections are found three forms which come within the admete group. 
The first or smoothest ( T. edwardsi Borradaile) is tolerably abundant on the coral reefs, though 
much less so than T. integra. The cardiac region is devoid of a crest, and there are only faint traces 
of its continuation on the branchial regions; fourth lateral tooth rudimentary, minute, often not 
discernible. Of the crests on the hand the two uppermost are granulous and each armed with two 
spines, those of one series - alternating with those of the other, the distal extremities armed with a 
blunt tooth; third crest obsolete; fourth strong and smooth in the young or in the old, obsolete except 
toward extremities of palm; fifth well developed, smooth; space between first and second crests finely 
granulous, also halfway to third crest (if such were developed) .
