In the Raya Island area where there 1S 4 mixed popu 
and striatus we have never found any intergrades of eis two. 1 en- 
close a definition explaining "Species and Speciation" and refer you 
to page 3, which carries three paragraphs explaining the concept of 
morphological and biological species. (See: Encyclopaedia Britanni- 
ca Vol. 17 pp. 449 to 455 "Species & Speciation.") The two species 
being sympatric in Raya, we evidently have a case here where "the 
mechanisms that thwart successful interbreeding" are in operation. 
About Conus thailandis, I give hereunder the distinct morphological 
differences:- 

crocatus thailandis 
Spire: pyramidal concavely exserted 
Shoulder: smoothly rounded angulate and broad 
Sides: straight slightly sigmoid 
Body shape: cylindrical and stoutly turbinate 
attenuated 
Color: saffron reddish-brown 
Markings: sprinkling of small irregular white blotches 
white subtriangular spots 
Max. reported 
size: 64mm 84mm 
Neither of the two species has any single morphological feature in 
common with the other. About all you can say is that Conus thai- 
landis is a member of the crocatus/lamberti complex. Just as you 
can place omaria, canonicus and others in the textile complex, but 
they are still separate valid species, each one. 
If some day you should visit Bangkok, I hope I may have the opportu- 
nity of placing before you the comprehensive evidence available 
showing how the conclusions that the species are new were reached. 
The many visitors I have already welcomed here have all left com- 
pletely satisfied.
