after whom we name the species. The original specimens of 

 this coral, with several others obtained from the Habbies-Howe 

 conglomerate, having been kindly placed at the disposal of the 

 above (R. E.,jun.), a short note was communicated on the 

 subject to the Royal Physical Society of Edinburgh*. 



In the note in question, T. Peachii was referred to pro- 

 visionally as a species of Alveolites ^ with the remark, " if it is 

 an AlveoUte it is even finer in texture than the very fine Car- 

 boniferous species A. depressa^ Flem." 



Form, and hoc. In pebbles of Silurian limestone contained 

 in the Old Red Standstone conglomerates of Habbies Howe, 

 Pentland Hills, near Edinburgh. 



Collected by, and in the cabinet of, Messrs. Brown, Hen- 

 derson, and R. Etheridge, jun.; also coll. Geol. Surv. Scotl. 

 Mus. Sci. and Art, Edinb., collected by Mr. J. Bennie. 



XXII. — Description of an apparently new Species of 

 Lamprocolius. By D. G. Elliot, F.R.S.E. 



Lamprocolius glaucovirens. 



A velvety black mark on the front extending between the 

 eyes ; top of head, occiput, and back of neck light metallic 

 grass-green, which graduates into a cold dark blue upon the 

 back. Auriculars metallic dark blue, similar to the back, but 

 less brilliant, edged with coppery red. Throat and upper 

 part of breast dark purplish blue, changing to dark greenish 

 blue along the sides, where it touches the grass-green of the 

 nape ; this greenish blue colour also extending like a band 

 across the upper part of the breast, enclosing the purplish-blue 

 throat entirely. Centre of lower part of the breast bright 

 metallic coppery red ; abdomen and thighs cold greenish blue. 

 Primaries have the outer webs shining bluish green, inner 

 webs dark brown with a greenish gloss, the tips light metallic 

 grass-green. Secondaries have their basal half metallic grass- 

 green like the tips of the primaries, then are crossed by a con- 

 spicuous broad velvety black bar ; remainder cold dark blue, 

 with the exception of the inner webs .of the two innermost 

 secondaries, which are light metallic grass-green like the 

 basal portion. The coverts are metallic green, each feather 

 tipped on the outer web with a velvety black spot, forming 

 two rows across the wing. Shoulders metallic bronzy green.
