on the Scandinavian coasts. The specimens, six in number, all of consi- 

 derable size, were described in detail, and the species was carefully compared 

 with the allied form M. vulgaris (the Common Ling). Mr. Holt next pro- 

 ceeded to describe the »recessus orbitalisa , an accessory visual organ of the 

 Pleuronectid Fishes. The organ in question was stated to be a highly elastic 

 saccular process of the membranous wall of the orbital cavity. It had been found 

 to occur in all the Flat-fishes examined, viz. the Halibut, Long Rough Dab, 

 Brill, Plaice, Flounder, Lemon-Sole, Dab, and Common Sole, and was 

 believed to occur in all Flat-fishes with well-developed eyes. Finally, Mr. 

 Holt spoke of an adult specimen of the Common Sole with symmetrical eyes, 

 and discussed the bearing of this specimen on ambicoloration. The specimen 

 in question, about 15 inches long, was perfectly normal in external con- 

 figuration , except that the left eye had retained its position on the left side 

 of the head, and was nearly opposite to the right eye. Antero-ventrally it 

 had been somewhat overgrown by the skin. The coloration was normal, the 

 right side being brown, and the left side white. — A communication was 

 read from Mr. St. George Littledale, containing field-notes on the Wild 

 Camel of Lob Nor, as observed during his recent journey across Central 

 Asia. — Mr. Oldfield Thomas gave on account of a collection of mammals 

 from Oman, S.E. Arabia, which had been transmitted to the British Museum 

 by Dr. A. S. G. Jayakar, C.M.Z.S., among which were examples of a new 

 Hare [Lepus omanensis) and of a new Goat of the genus Hemitragus , pro- 

 posed to be called Jayakari, after its discoverer. Altogether 1 7 species were 

 represented in this collection , from a locality of which very little was 

 previously known. — P. L. S dater, Secretary.
