NATURAL HISTORY SOCIETY OF GLASGOW. 39 



Dicranodontium lo7igirostre, known only formerly in British bryology 

 to grow near the Lakes of Killarney, he had found in three differ- 

 ent places. Among the interesting species alluded to besides the 

 foregoing, there were an arboreal form of Dicrmmm polycarjmm, 

 Brijum Duvalii, and a new variety of either Orthotrichum crispimi 

 or Orthotrichum crisjmhtm, of such a nature as to lead to the union 

 of these two species. 



May 24th, 1862. 



Mr John Gray, Vice-President, in the chair. The following 

 gentlemen were elected members: — Messrs James Bain and A. C. 

 Millar, resident; and Mr Alexander Fisher, Galashiels, corres- 

 ponding. 



SPECIMENS EXHIBITED. 



Mr David Robertson exhibited a very remarkable specimen 

 of Haliclwndria Ventilabrum, which he had procured from deep 

 water off the Cumbrae Islands. It measured 12 inches across the 

 mouth of the funnel. Another specimen of this fine sponge, perfect 

 in condition and of unusual symmetry, was also laid on the table, 

 both objects exciting a considerable share of attention. 



Mr James Thomson exhibited several interesting specimens of 

 sandstone, burrowed into by annelides. These specimens were 

 procured from the neighbourhood of Bathgate, to the north of 

 Bathgate Hill, the sandstone occurring in thin layers, in the 

 midst of bituminous shale of 20 feet in thickness, overtopping 

 several bands of limestone. The specimens showed the overlying 

 bituminous shale deposited in the burrows of the creatures. 



Mr John Gray, the vice-president, exhibited three species of cir- 

 ripedia, two of them parasitic on the South Sea whale, namely — 

 Coronula halcenaris, and Tubicinella halcenaris — the latter burrowing 

 in the blubber; and Chelonobia testudinmia, parasitic on the back 

 of turtles.
