Paramithrax peronii, M.-Edwards. Miers, Cat. N.Z. Crust., p. 5; Index Faunæ N.Z., p. 247.
Several specimens from Channel Island, 25 fathoms, and one from 30 fathoms, appear to belong to this species, but they are very small, the largest having the carapace not more than 15 mm. long.

One small male specimen from Channel Island, Hauraki Gulf, 30 fathoms, appears to agree well with the description. As is frequently the case with males, this specimen was found free and not in a bivalve shell.
It is perhaps worthy of note that Heller's “Novara” specimens, which he identified with the P.pisum of Europe, were from Auckland, found in Mytilus.
Ebalia lévis, Bell. Miers, Cat. N.Z. Crust., p. 56; Index Faunæ N.Z., p. 251.
Three specimens from Channel Island, 25 fathoms. I have also two specimens dredged off the Poor Knights Islands in 60 fathoms by Captain Bollons early in 1905.
Through the kindness of Mr. F. E. Grant I have been able to compare this species with specimens of E. tuberculosa (Milne-Edwards) taken off Sydney at the depth of 300 fathoms; from these E. lævis may be distinguished by the smoother carapace, and by having the posterior margin produced so as to give the appearance of three obtuse teeth. Mr. G. M. Thomson has recorded E. tuberculosa from Dusky Sound, 40 fathoms. It was taken by the “Challenger” at station 167, about a hundred and fifty miles west of New Plymouth, in 150 fathoms.*
