I should have liked in any family except Lumbricidae. Of 

 this family — the Earthworms proper — I have now a list of 

 14 species.^ As regards the many species of Enchytrseidae 

 occurring both inland and on the shore, only two or three 

 have as yet been made out, Enchytrceus albidus, Henle, and 

 Lumbricillus verrucosus (Clap.), however, are common on the 

 beach at Dalmeny and Aberdour. Similarly, a few only 

 of the aquatic forms have been determined.^ Altogether, 

 my list of Oligochasta runs to about 30 species, and before 

 it is published there ought to be some to add. Were a 

 qualified zoologist to take the group in hand, he would 

 probably be able, in a comparatively short time, to announce 

 a list of 80 to 100 species. 



HIEUDINEA. 



It would seem that more leeches were known to Sir J. 

 Dalyell from the ponds and ditches in the neighbourhood of 

 Edinburgh than have been noted since. After a good deal of 

 searching, I have met with only five species, namely. — 

 Glossiphonia {Glepsine) stagnalis (L.), G. complanata (L.), 

 Hemiclepsis tessellata (MiilL), Hcemopsis sanguisuga (L.) (the 

 well-known horse-leach), and Herpoldella octoculata (L.), all 

 more or less common, and already on record,^ Dalyell 

 mentions other three, namely, the medicinal leech, Hirudo 

 medicinalis, L. (he figures a specimen from Loch Leven, and 

 also cites a pool near Lake of Menteith as then a locality 

 for the species), H. vitrina (probably merely a variety .of 

 tessellata), and H. flava ( = Gl. marginata . (Miill.)*). Un- 



^ I have to thank Mr F. E. Beddard and the Rev. Hilderic Friend for help 

 in naming these. To Dr Michaelsen I am indebted for the determination of 

 HelodriliLs oculatus, Hoffm. For list see further on in this vol. 



- In a short paper entitled "Additions to Scott and Lindsay's list of 

 Animals found in the Upper Elf Loch" {Ann. Scot. Nat. Hist., 1905, p. 215, 

 and 1906, p. 57), I recorded Stylaria Ictcustris (L. ), Lumhriculus variegatus 

 (Miill.), and JSolosomct hemprichi, Ehr. S. Macadam {Proceedings of this 

 Society, iii. p. 234) and T. Scott {Uh Fish. Bd. Rep., pt. iii. p. 273) have 

 recorded Tuhifeo: rivulorum, which I have also found abundantly at Loch- 

 end, etc. Dr Ashworth has shown me Choetogaster limncei from the marl-pit 

 near Davidson's Mains.
