chain. It is somewhat remarkable that this interesting and 

 distinct moss should be confined to this narrow belt of rocks of 

 trap formation, stretching across the country, at intervals, be- 

 ginning with Arthur's Seat and ending with Dumbarton Castle; 

 the same is true of one or two others of the Grimmice enumerated. 



Dr Young exhibited specimens from a large collection recently 

 presented to the Hunterian Museum. This collection, formed by 

 Dr Dug^s, illustrates the fauna of the vicinity of Guaguanato, in 

 Mexico, and was presented by him to the museum through Mr L. 

 M'Gowan, British Consul in Mexico. The specimens include 

 several hundred insects; above tliirty species of amphibia and 

 reptiles; skins exquisitely prepared and ready for stuffing, of 

 thirty-three species of birds and mammals. This magnificent gift 

 will necessarily take some time to arrange; but Dr Young 

 exhibited two species of tree frogs and a toad, remarking on their 

 geographical distribution, and the mode in which they represent 

 nearly allied species in the old world. Two species of horned 

 lizard are now in the museum, one {Phrynosoma orhiculare) from 

 Duges' collection; of the other (P. Harlenii), two specimens were 

 kept alive for some months by Mr Young, but persistently refused 

 food. Two out of the five species of Tropidolepis, a lizard closely 

 related to Phrynosoma, were also shown. Dr Young promised to 

 exhibit the rest of the collection as they were arranged and 

 mounted. 



Mr Edward R. Alston exhibited a specimen of Daubenton's Bat 

 {Vespertilio Dauhentonii), which was taken on Glasgow Green in 

 1864; and made some remarks on other Scottish sj)ecies of a like 

 interest. 



Mr John Young exhibited a finely-preserved specimen of a fossil 

 fruit, obtained from the marine limestone shales at Newfield 

 Quarry, High Blantyre. This fruit somewhat resembles in size 

 and form the Trigonocarjmns, a genus of coniferous fruits found in 

 the coal measures, of which he exhibited some illustrative speci- 

 mens from the Ayrshire coal-field, but diff'ers from them in posses- 

 sing at the top of the fruit eight sharp ribs, which extend about 

 one-third along the length of the shell, the rest of the surface 

 being smooth, and having the calyx well marked at the base. 



Mr Young also made some remarks upon the very rare occur- 

 rence of fossil fruits of this class in the marine limestone shales of 

 Scotland, and stated that the specimen exhibited, which had
