314 The Irish Naturalist. 



remembered him well as a schoolfellow, but told me there was 

 no representative of the family left, and could give me no 

 information as to an}^ of M'Calla's collections. M'Calla, as 

 Harve}^ states, died from cholera in 1849, a comparatively 

 young man. I was shewn, in the churchyard at Roundstone, 

 a substantial monument erected, as the inscription stated, to 

 M'Calla's memory by his admiring brother naturalists. Un- 

 fortunately Roundstone is by no means easy of access,^ being 

 50 miles west of Galway, the nearest railway station, and also 

 off the direct mail-car route to Clifden. Beyond the break- 

 down of the mail-car shortly after leaving Galway, a conse- 

 quent loss of time, and a drenching later in the day, I reached 

 Roundstone without trouble. Once there, there is every 

 reason to be satisfied with the field of work. I was fortunate 

 in obtaining the services of a man, Creelish Martin, who, 

 besides being a reliable and experienced sailor, understands 

 the working of a dredge, and has a very good knowledge of 

 the sea-bottom as regards its physical and, to a certain extent, 

 natural history features. With his help, and the use of a 

 sailing boat (from J. Cloherty), I got several days' dredging in 

 Roundstone and Birturbui bays. Roundstone Bay, as readers 

 of Harvey's Phycologia Britamiica know, is characterised 

 by a large development of the calcareous red algae known as 

 the Corallinacc^ (formerly as Ntillipores), two species, 

 Lithotha7miio7i fasciailaticvi, Aresch., and Lithotham7iion 

 agaricifonne, Aresch., being confined to the district, and first 

 discovered^ there by M'Calla. Of the twenty-five species of 

 CorallinacecE , known at present to occur in British waters, the 

 great majority are to be found in the bay. My object in 

 going to RoundvStone was rather to search for species added to 

 the marine flora of Britain since the publication of Harvey's 

 great work, the Phycologia Britan7iica, in 1846-51, but not yet 

 recorded from Ireland. Many of these species are minute 

 epiphytic forms, often only to be recognised by a detailed 

 microscopic examination. As I stated in a former article in 



^ The light railway from Galway to Clifden, when completed, in 

 August, 1894 (?), will take one within five miles of Roundstone. 



- I showed my man, Creelish, Harvey's coloured figures of these and 

 other species, and was not a little pleased to see them brought up in our 

 first hauls, the coralline being in several fathoms of water, north of 

 Roundstone.
