MARINE FAUNA. 



A beginning only has been made, but a considerable number 

 of names has been added to the preliminary list published by 

 Prof. Parker and Hans Gadow in the College Magazine for June, 

 1881. Our marine fauna is subject to these disadvantages, viz., 

 the exposed nature of the coast, the lead poisoning of the rivers, 

 and the absence of limestone. The rock-pools in front of the 

 College have received most attention. We hope to attempt 

 dredging before long : up to the present only shore-collecting has 

 been tried. 



Of Nudibranchs, Doris tuberculata and Eolis papillosa have 

 been met with in fair numbers, while the following species have 

 also occurred : — Doris aspera, Doto coronata, Goniodoris nodosa, 

 Flahellina drummondi, Ancula cristata. 



From their abundance and variety, there is every reason to 

 believe that the Worms, more especially the Polychaetes and 

 Nemertines, would yield excellent results ; but as we do not 

 possess Mcintosh's Nemertines, or any other of the monographs 

 published by the Eay Society, we are quite unable to identify 

 them. The loan of any such works would be much appreciated, 

 or we would forward gatherings to any specialist v/illing to 

 undertake the naming of the species. On Jan. 10th, 1893, the 

 little red archi-annelid, Dinophilus tmniatus, was found in great 

 abundance. 



Of Turbellaria, Leptoplana tremellaris occurred in plenty at 

 the end of November last, seven specimens being taken under 

 one stone. The Clarach ditches have yielded two fresh-water 

 forms, Polycelis nigra and Dendrocoelum ladeum ; and from the 

 same locality, with other Entomostraca, Lynceus sphoiricus has 

 been obtained. So scarce are Echinoderms, even the common 

 starfish, Asterias rubens, that we were surprised to find this species 

 in large numbers washed up on the end of the Causeway at 

 Wallog on Feb. 11th. The same day several examples of Astero- 

 peden were obtained from Borth beach. We hope to give a much 

 less meagre report under this heading on the next occasion. 



BOTANY. 



Little attention appears to have been paid, hitherto, to the 

 flora of our district, but an attempt is now being made to form a 

 complete list of the flowering plants which occur within a radius 

 of twelve miles of Aberystwyth. The list now includes 340 

 species, and, as frequent additions are being made, it seems best 

 on this occasion only to mention a few of the plants most worthy 

 of note, in the hope that we may be able to publish a complete 

 flora at no distant period. From a botanist's point of view, the 

 district is not a rich one ; many plants common in most parts of 

 England are entirely wanting. The uniformity of the geological 

 formation (and especially the absence of limestone) is largely
