12 C. HEDLEY. 



David Sharp 1 from 1882 to 1886, in recognition of his 

 researches named the following: — Lissotes helmsi, Cicin- 

 dela helmsi, Anchemenus helmsi, Steropus helmsi, Zolus 

 helmsi, Tomus helmsi, Adelopus helmsi, Dasytes helmsi, 

 Pycnomeras helmsi, Periatrum helmsi, Somatidia helmsi, 

 Anagotus helmsi, Icmalius helmsi, and Pentarthrum helm- 

 sianum. Among many novelties in land shells furnished 

 from Greymouth to Oapt. Hutton, there was included Zonites 

 helmsi. 2 In 1894 a marine shell from New Zealand was 

 called Acmaea helmsi by Mr. E. A. Smith, and in 1915, the 

 writer named an Australian shell Erycina helmsi. 



In November 1888 he came to Sydney and entered the 

 service of the Australian Museum. Early in 1889 he was 

 despatched on a collecting excursion to Mount Kosciusko, 

 an interesting account of which has been published. 3 Here 

 he gathered a large series of the hitherto unknown alpine 

 fauna. One discovery of especial interest was the primi- 

 tive isopod Phreatoicus australis. Kosciusko exercised an 

 attraction for Helms for the rest of his life, and he returned 

 to it again in 1893, and again in 1901. He wrote an article 

 "On the recently observed evidences of an extensive glacial 

 action at Mount Kosciusko." 4 This evidence was subse- 

 quently doubted by Milne Ourran, but was finally vindicated 

 in an important paper in which Helms was associated with 

 Professor David and Mr. Pittman. 5 The natives of the 

 Monaro Highlands were described in his Anthropological 

 Notes. 6 He summed up his knowledge of the climate, 

 fauna and topography of the Range in a memoir "The
