Tliis species, which was first described by Riippell from a 

 specimen obtained at Massowah, was shortly afterwards^ described 

 by Uumeril and Bibron from Bengal as Il.coctcei. Klunzingcr, 

 in 1878, again recorded it on the coast of the lied Sea at Koseir, 

 and since then it has been observed at Aden and at Maskat, and 

 has been found at Fao and Jask in Persia.
