(Stephenson and Hudson, 1957; Stephenson, 1961a). In the single 
small male, the pleopod differs slightly from that figured in Stephenson 
and Hudson (1957) in possessing fewer subterminal bristles. On the 
inner side, only five stout spines are present, while on the outer side 
there are only five bristles, two of which are large. 
Barnard’s description of 7. inhacae from Inhaca Bay in South 
Africa did not include comparison with T. bowmert. The distinctions 
between the two species seem to be solely in the ornamentation of the 
hand of the cheliped. In 7. inhacae, five blunt spines and one outer 
ridge are described by Barnard, while there are three spines and 
three ridges in 7. bouviert. Throughout the genus Thalamita, spines 
on the upper surface of the cheliped are invariably borne upon partial 
or complete carinae, and the presence of five spines necessarily implies 
more than one carina, with a suspicion of the usual two on the upper 
surface. These are certainly present in the Australian and present 
material. Spines are invariably subject to wear and capable of being 
reduced to obscure tubercles. Evidence of this is given in the details 
of the present collection. 
Crosnier (1962) has examined female syntypes of T. bowert and 
provided the final confirmation of the synonymy.
