Chilton. — Crustacea from the Chatham Islands. 273 



white line about 2 mm. wide, extending from the cephalon all 

 through the pereion and half-way along the pleon, the rest of 

 the body reddish-brown. Another has white markings on the 

 margins of the epimera, the third (female) without any white 

 markings. 



Iais pubescens, Dana. Index Faunae N.Z., p. 264. 



Numerous specimens found in the bottle, in which the only 

 Sphaeromids were the specimens of (?) Isocladus spiniger, Dana, 

 mentioned above, and I have no doubt they were commensal 

 on this species. They appear quite the same as those found 

 on Sphmroma gigas, Leach. This species occurs throughout 

 the southern seas as a commensal on several Sphaeromids. Mr. 

 Stebbing has given a full description of it in the Proc. Zool. 

 Soc, 1900, p. 549-51. 



Deto novae-zealandise = Oniscus novw-zealandia?, Filhol, " Mis- 

 sion de l'lle Campbell," p. 441, pi. liv, fig. 7. 

 Among some Crustacea sent from Te Whakuru Beach by 

 Miss Shand (August, 1903) are three imperfect specimens that 

 evidently belong to this species. The rounded swollen granular 

 prominence on each side of the 1st segment of the mesosome is 

 very characteristic, and agrees well with Filhol's figure and 

 description : " Le premier anneau du corps presente chez certains 

 sujets, de chaque cote, a ses extremites, une saillie arrondie, globu- 

 leuse, couverte de tres fines granulations." 



Actcecia aucMandice, G. M. Thomson (Trans. N.Z. Inst., xi, 

 p. 249), which I provisionally placed under Scyphax in 1901 

 (Trans. Linn. Soc, viii, p. 126), also belongs to the genus Deto, 

 and is distinguished from D. novce - zealandios, among other 

 points, by the absence of the rounded prominences on the 1st 

 segment of the pereion. I am preparing a fuller paper on these 

 and other species of Deto. 



Oniscus punctatus, C M. Thomson. Index Faunae N.Z., p. 265. 

 Two or three specimens from Pitt Island (Dr. Dendij). Dr. 

 Budde-Lund informs me that he has established a new genus, 

 Phalloniscus, for this and other allied species, but I have not 

 yet received the paper in which this genus has been published. 



Armadillo speciosus, Dana. Index Faunae N.Z., p. 266. 



In 1901 I referred some specimens from the Chathams in 

 Mr. Thomson's collection to this species with some hesitation. 

 I have since received further specimens of the same kind from 

 Pitt Island, collected by Dr. Dendy, and think they must belong 

 to Dana's species, but it is very difficult to know exactly what 

 species was intended by some of the early descriptions. Dana's 

 specimens were from the Bay of Islands.
