of about thirty years from the original date of supposed collection. 

 We cannot admit either species to a permanent position in our 

 records without corroboi'ative evidence. 



Another species, a Flanorbis, found near Melbourne, stated to be 

 introduced, is, Mr. Brazier informs me, an indigenous Segmentina. 



Another European species of slug is found with us, viz., Limax 

 hecis, MiilL, (syn. L. Queenslandicus, C. Hedley, P.R.S.Qld., 

 1888; L. Rarotonganus, Heyneman), an exceedingly glossy form 

 about f of an inch long. Recorded from Queensland, N.8.W., 

 Victoria, and New Zealand ; very widely distributed. We 

 may, I think, consider this an indigenous form. It is found 

 in very out of the way places, and far away from the coastal cities 

 in such situations that we can but consider it as indigenous. 

 Mr. Hedley is quite of this opinion, and I am disposed to agree 

 with him. 



Godwin- Austen describes a Helicarion under the specific name 

 of Helenw from Sydney ; it is a synonym of H. hyalinus. Mr, 

 Brazier states that the examples obtained by Godwin-Austen 

 were from a colony introduced from Queensland. 



We may note that Professor Hutton describes a Testacella 

 (species vagans) from gardens in the vicinity of Auckland, N.Z , 

 a carnivoi'ous slug-like mollusc carrying a small ear-shaped shell 

 on its tail. Representatives of this genus usually live in gardens, 

 under the surface of the ground. There are three distinct British 

 forms. Mr. Cheeseman of the Auckland Museum thinks their 

 species may prove to be one of the European forms, possibly T. 

 taaugei, Fer. 



A species of slug has been described by Gould (Otia Conch.) 

 from Parramatta, as Limax olivaceus. The length is given as | 

 inch ; Tryon, however, (Man. Conch. Vol. I.) gives 2-5 inches as 

 the size, and figures (pi. 50, f. 81) a slug corresponding with the 

 size given. If the latter be correct it is probably a form of 

 L. Jlavus, L. ; whilst if Gould's measurement be correct, it is 

 probably L. Icevis. The latter form, it may be noted, is found in 

 the original locality. Tate (in P.R.S. Tasmania, 1880) has also
