EXCURSION TO YAN YEAN. 



The following reports were unavoidably omitted from the 

 report in the last Naturalist, page i6o. 



On the same page the word Potomageton should read Pota- 

 mogeton. 



Botany. — Altogether some thirty-three plants were found in 

 bloom. In a swampy brancii of the Plenty fine specimens of the 

 Loose-strife, Lythrum salicaria, w.ere growing, and some within 

 reach collected ; also L. hyssopifolium and Veronica gracilis. 

 Under the pines along the western side of the reservoir. Glycine 

 clanidestina was plentiful. Nearer the water grew the umbellifer 

 Uryngium vesicnlosnm, having a thistle-like appearance. At the 

 southern end of the lake, on some stony ground, grew Cussinia 

 theodori, Helicliryswrn obcordaiuni, and other shrubs in a part 

 which in the springtime would be worth visiting, and would 

 probably yield many specimens.- — K. Cowle. 



Geology. — The Silurian rocks in the neighbourhood of Yan 

 Yean consist of brown sandstones, mudstones, and olive and blue 

 shales. These are in places highly fossiliferous. Some members 

 of the party visited the heaps of material which, nearly fifty years 

 ago, were thrown out of the shafts when excavating the tunnel 

 which conveys the water of the Plenty River into the reservoir. 

 After some hammering and sorting the following specimens were 

 secured, the most noteworthy being a fine Trilobite, found by 

 Master J. Tuckett, and a specimen of Hyolithes, of a species until 

 lately found only in Bohemia, found by Master W. D. Chap- 

 man : — Phacops, sp. ; Encrinvrus, sp. (fragments of pygidia 

 common) ; Chonetes, near melbournensis, Chap. ; Bellerophon, 

 sp. ; and Hyolithes novellns, Barrande. At the southern end of 

 the reservoir, in a cutting on the Arthur's Creek road, other frag- 

 mentary fossils were found, including a cast of a Murchisonia 

 and a small specimen of Retzia liopleura, M'Coy, sp., but time 

 did not allow of an extended search. — F. Chapman. 



EXCURSION TO BEAUMARIS. 



A party of twelve members of the Club visited Bt-aumaris on 

 Saturday, the 20th February, our main object being the collection 

 of various marine organisms such as might be carried home for 

 further observation under the microscope. The weather was very 

 pleasant, but the condition of the tide was particularly unfavour- 

 able, as there were only two hours before high water when we 

 arrived at our destination. We decided to devote the time to the 

 small inlets near at hand, rather than to the bay towards Mentone, 

 as we had at first intended if the tide had been favourable, since 

 the tide-streaks which can be gathered at the latter locality, con-
