454 THE ZOOLOGIST. 



With the Gulls were a few Terns, which I was unable to 

 identify ; they were about the size of the Indian Eiver Tern 

 {Sterna seena), with short-forked tails, and of a nondescript 

 grey colour, with no particular markings, save a black 

 mark near the eye ; the bill was black. It is possible that 

 they were Gull-billed Terns {Sterna anglica) in non-breeding, 

 dress. 



April 28i/i.— Ara.bian Sea. The only bird seen all day was 

 a small passerine, which followed the course of the ship for 

 for about half an hour against the wind ; by flight, appearance, 

 and note it seemed to be some species of Wagtail, yellowish in 

 colour, with white in the tail, and perhaps a chestnut head. 



April 29</?. — Arabian Sea ; no birds seen. 



April QOth. — Arabian Sea. A few Black and White Gannete, 

 namely, a party of three and a single bird, were doubtless the 

 Masked Booby {Sula cyanops). 



A good many Shearwaters {Pu-ffinus sp, ?) were observed 

 during the day. 



May 1st. — Arabian Sea ; a party of three of the Gannets 

 seen, as well as one or two solitary individuals. Shearwaters 

 were plentiful. 



May Q^nd. — Arabian Sea. Position at noon : Lat. 14°'00',. 

 long. 57°-03' ; 358 miles to Aden. 



About 10 a.m. a Nightjar {Caprimulgus sp.?) came aboard,, 

 and flew about for some ten minutes, perching occasionally ; 

 after this it disappeared, but must have hidden somewhere in 

 the ship, as it was flying about both in the morning and evening 

 of May 3rd. I did not see it on the 4th, but it was still with 

 us before breakfast on May 5th — a good example of an " assisted. 

 passage." 



Shortly before dusk a party of nine Bee-eaters, which looked 

 like Merops philippinus, passed flying eastwards low over the sea 

 with the typical hesitating flight of the species. 



Fewer Shearwaters were noted than yesterday, and one or 

 two Gannets, in addition to a party of four, which were resting 

 on the sea. 



May drd. — Arabian Sea. A male Eose-ringed Parroquet 

 {Palaornis torquatus) was flying round the ship and settling oa 

 the rigging ; it was doubtless one of the Lascars' birds.
