I follow Prof. J. G. Hidalgo's views as to the nomenclature of this species, which 

 has heen almost universally known as C. cruenta, Gmel. Gmelin, however, in 1790 

 thus re-named G. erroiies, Linne, 1758, and the name cruenta therefore falls.

 The specimen from the last-named island is in remarkably fine condition. Always a 

 rare species. Prof. Hidalgo * names Pulo- Condor, the Philippine and Loyalty Isles as 

 the only known localities. The discovery of these specimens in the Sealark 

 Expedition therefore extends the range of distribution immensely to the soutla 

 westward.

At the Cargados Station (B 3) an unnamed variety, subtransparent, of a pinkish-yellow 

 hue, occurred. The examples, also, of the variety mascarena, of ri'markable depth of 

 colour and brilliancy, from the Chagos Archipelago prompt one to the belief that here 

 the species reaches its highest development. 



It is never a common species on the coast of Hindustan, though reported from Madras 

 and the island of Ceylon. It is likewise an inhabitant of the Laccadive and Maldive 

 Islands, of the Andamans, and, further eastward, of Siam, Penang, Cochinchina, China,
