- Phegopteris Dryopteris, Fee.) Besides these, Mr. Wright 

 states there are found the Winter Green (Pyrola media, Sw.), 

 the Bird's Nest Orchid {Neottia Nidus-avis, Rich.), and the 

 Wood Melic Grass {Melica uniflora, Retz.). 



" We emerge from the glen a little beyond the point where 

 the railway is carried over it on a fine bridge, and after a walk 

 of about 3J miles reach Hurlford railway station, the total 

 walk being between 9 and 10 miles at a low estimate." 



Marine Biological Station, Keppel Pier, Millport, 23rd 

 August, 1902. — The members of this excursion arrived in two 

 detachments, the first and largest coming by steamer arriving 

 at Keppel Pier at 10 a.m. They at once proceeded on board 

 the "Mermaid," which was lying off the station, and under the 

 guidance of Mr. Alex. Gray, were taken to the well-known 

 dredging ground at the Tan Buoy. Here a short haul was 

 taken with the square, iron-lipped dredge, which brought 

 up a great quantity of gravel, shells, and Melobesia. The 

 most interesting creature obtained here was probably the 

 nest-building bivalve Mollusc, Lima Mans, Gmel., with its 

 pretty white shell and long fringe of scarlet tentacles. A 

 good many Crustaceans and Brittle-stars w r ere also obtained 

 here, and, while examination of them was proceeding, the 

 " Mermaid " steamed to the east side of Bute, near Mount 

 Stuart House, where two hauls of the trawl were taken at 

 depths of 15 and 25 fathoms. The ground here was very 

 productive, especially in Echinoderms, the most abundant form 

 being the ordinary Spiny Sea Urchin, Echinus esculentus, L., and 

 the little green Urchin, Echinus miliar is (Gmel.) Several speci- 

 mens of the Heart Urchin, Brissopsis lyrifera (Fork), came up in 

 the deeper haul. This species is a good type of the irregular 

 Urchin, just as the Echinus is of the regular Urchin, and when 

 both forms are placed side by side they make an instructive 

 object lesson. 



Many specimens of the common five-fingered Star were captured, 

 also the handsome large spiny Star, Asterias glacialis (O. F. M.), 

 together with both species of Solaster, viz., the many-rayed 

 Sun Star, S< papposus (Fabr.), and the purple Sun Star, S. 

 endeca (L.). The beautiful strawberry-coloured Cushion Star,
