STEBBING ON CRUSTACEANS FROM [Jail. 19, Young larvae were obtained of the following species:-Attacus atlas, A. mylitta, A. pernyi, and some hybrids said to be hybrids between Attacus pernyi and A. mylitta, and between A. pernyi and A. roylei, Actias selene, Samia ceanothi, and hybrid Samia cecropia and S. ceanothi. Of these, Attacus pernyi and the hybrids only were reared, the other specimens all died. Every attention was given to them, and I regret to have to express m y opinion that the present Insect-House is not a suitable building for rearing young larvae. At the same time, it must be borne in mind that the past season was, in consequence of the long drought, bad for rearing larvae, as the leaves of the food-plants became hard and dry early in the summer. Apart from this, the leaves of all trees growing in or near the Gardens get very dirty with smoke, and although the precaution is always taken to wash the food before using it, the leaves are not so fresh and good for feeding as those obtained from the open country. The larvae of Attacus pernyi were reared upon the English Oak when the leaves were young and succulent, and they grew verv rapidly and did well. The so-called hybrids of Attacus pernyi and Attacus roylei were reared, and a good number of cocoons obtained. The hybrids (?) of Attacus pernyi and Attacus mylitta did not do so well, and only three cocoons were obtained. One insect from each of these cocoons has emerged up to the present, and these are, in m y opinion, Attacus pernyi pure. I tried to obtain pairings of A. pernyi with females of A. mylitta, but did not succeed, although the insects were in the finest condition, and the males of A. pernyi were most energetic in their endeavours to pair with the females of A. mylitta. I had no opportunity of trying this experiment with Attacus roylei, as I had not any of that species. I am sorry to have to record the death, in November, of the very fine Mygale fasciata, which was presented to the Society by Mr. H. R. P. Carter, in January 1885, and of which a life-sized figure was published in the 'Field' of April 25, 1885, together with some notes by Mr. W . B. Tegetmeier, F.Z.S. The colours of this Spider during life were very beautiful. A communication was read from the Rev. T. R. R. Stebbing, containing descriptions of some new Amphipodous Crustaceans from Singapore and New Zealand. The species were shortly described as follows :- 1. BYBEIS KALLARTHRUS, sp. nov. This new Amphipod was brought from Singapore by Brigade- Surgeon S. Archer. The most striking peculiarities are the doubly sinuate lower margins of the fourth pair of side-plates, the branchiae carrying on their surfaces rows of overlapping secondary vesicles, and the third uropods, in which the inner margin of the outer branch and the outer margin of the inner branch are much ornamented.
