Show 4 ME. P. CHAPMAN ON SOME [Jail. 15, two birds being sexes of tbe same species.' I may add that the present specimen is the only one of this hybrid that I have ever handled, or, to the best of my recollection, ever seen." The Rev. T. R. R. Stebbing exhibited a specimen of a species of Pervpatus from Antigua. The following papers were read:- 1. On some Foraminifera obtained by the Royal Indian Marine Survey's S.S. 'Investigator/ from the Arabian Sea, near the Laccadive Islands. By F R E D E R I CK C H A P M A N , E.R.M.S. [Eeceived November 7, 1894.] (Plate I.) On the 25th of July, 1893, 1 received some samples of deep-sea soundings from Mr. T. H. Holland, F.G.S., Assistant-Superintendent of the Geological Survey of India, who, in conjunction with Dr. Alcock, Surgeon-Naturalist in the Royal Indian Marine Survey Department, has very kindly placed the material in my hands for description. The results of a somewhat exhaustive examination of the soundings appear to be of sufficient interest for publication. Moreover, the locality from whence these soundings were obtained is sufficiently out of the path of former expeditions to make the list useful. The soundings were obtained by the Royal Indian Marine Survey's steamship 'Investigator' from a limited area near the Lakadivh (Laccadive) Islands, viz., 15° 30' 4" to 8° 21' 3" N. lat. and 75° 42' 5" to 71° 09' 3" E. long. The depths at which the soundings were obtained have not been recorded, but they did not exceed 1238 fathoms. This absence of the record of depths is explained by the fact that the material was originally sent to Mr. Holland for his opinion regarding the supposed occurrence of submarine volcanoes in that part of the Arabian Sea, the search for Foraminifera being undertaken subsequently. Samples of the soundings were sent to me after having been washed for the purpose just stated. Mr. Holland has also kindly furnished me with the following notes concerning the temperature of the area from whence the material was taken.-" The lowest bottom temperature recorded was 37°F., several times at about 1130 fathoms; the surface temperature being about 78°-80° F." The material was sent in six bottles, each sample appearing to represent a mixture of several distinct soundings. The samples are labelled thus:- |
