668 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Crustacea. 



to this species was obtained on Stewart Island during the expedition, and from 

 a comparison of the figures given in Gay's " Historia di Chile " it is evident that 

 Oniscus hucculentus, Nicolet, and Oniscus tuherculatus, Nicolet, from Chili, are male 

 and female either of this same species or of one very closely allied. 



Other species of the genus are found at the Cape of Good Hope ; at St. Paul, in 

 the New Amsterdam Group ; and in Australia. 



Fam. Oniscidae. 



Genus Oniscus, Linnaeus, 1767. 



Distribution. — The genus Oniscus is cosmopolitan, but the section to which 

 the following species belongs is, so far as at present known, confined to Australia 

 and New Zealand. 



Oniscus punctatus, G. M. Thomson. 



Oniscus punctatus, G. M. Thomson, Trans. N.Z. Inst., xi, p. 232, pi. xa, 

 fig. 3, 1879; Chilton, Trans. Linn. Soc, viii, p. 133, pi. xvi, fig. 2, 

 1901 ; Trans. N.Z. Inst., xxxviii, p. 273, 1906. 



Numerous specimens were obtained at Auckland Island, and are quite the same 

 as those found in New Zealand, where the species is very widely spread. The same 

 species, or one very closely allied, is also found in Tasmania and Australia. 



This species does not come strictly under the genus Oniscus as now restricted. 

 Dr. Budde-Lund, by letter, some years ago told me that he was establishing a new 

 genus, Phalloniscus, for its reception, but I am not aware whether this genus has 

 yet been published. 



Genus Cubaris, Brandt, 1833. 

 Distribution. — Cosmopolitan. 



Cubaris rugulosus, Miers. 



Cubaris rugulosus, Miers, Ann. & Mag. Nat. Hist., ser. 4, xvii, p. 225, 1876 ; 



Cat. N.Z. Crust., p. 96, pi. ii, fig. 5, 1876. Armadillo rugulosus, Chilton, 



Trans. Linn. Soc, viii, p. 147, pi. xvi, fig. 7, 1901. Spherillo rugulosus, 



Budde-Lund, Bevision of Crust. Isopoda Terrestria, iii, p. 65, pi. vii, 



figs. 37-39, 1904. 



This species appears to be common in the Auckland Islands. Professor Benham 



gathered it near Port Boss, in the north of Auckland Island ; under logs at Carnley 



Harbour, in the south ; and one specimen on Disappointment Island. It also occurs 



in Campbell Island, where it was collected by myself and by Messrs. Chambers and 



Des Barres. 



These specimens appear to be quite the same as those from the main islands 

 of New Zealand, where the species is widely distributed, and is particularly abundant 

 in the more southern parts. Dr. Budde-Lund has revived Dana's name Sfherillo 

 for a section of the genus hitherto known as Armadillo, but as I do not quite under- 

 stand the characters given by him in the definition of Spherillo, and as the name 

 Cubaris is older and has been adopted by Stebbing and Caiman, I also have used it.
