The foregoing list is doubtless very imperfect, and it will be ob- 

 served that it does not contain a single Chelonian, either from the 

 land or water, and no marine snakes. Every section of the fauna 

 of Aden is of extreme interest o\^iag to the geographical position of 

 the locality and its proximity to the African coast. The question 

 whether any sea-snakes are found on the coast is one well worthy of 

 the attention of any resident at Aden interested in the geographical 

 distribution of animals. Sir Lambert Playfair informs me that he 

 has never heard of them at Aden or any^vhere in the Eed Sea, but 

 that he has seen them oflE the coast of Arabia, when going from 

 Zanzibar to Bombay. They are unknown at the former localit}'. 

 Colonel TerbuT}' says he has never met with a sea-snake at Aden, 

 and that he does not believe that they exist there, or he would 

 certainly have met with them when he was collecting marine shells 

 and seining. Sea-snakes are common at Muscat, indeed they occur 

 there rather in profusion. To what cause is their apparent absence 

 at Aden to be attributed ? If not entirely absent from the Aden 

 sea they must be extremely rare, as many good observers have 

 visited both sides of the Gulf and not a single instance of their 

 occurrence has been recorded in zoological literatiu-e.
