Iconaxiopsis kermadecensis sp. nov. Figs. 1 and 2.

In general resembling I. andamanensis Alcock, but apparently differing in the following points: The rostrum not quite reaching to the end of the second joint of the antennular peduncle, triangular, margins towards the apex smooth, but with a prominent tooth on each side at the base of the rostrum, a slight ridge being continued backwards on the carapace from each of these lateral teeth; slightly further back are 3 smaller teeth closely placed in a transverse row on the carapace, one central and two lateral with slight indications of ridges extending backwards from them. There is a small tuft of long hairs on the inner side of the base of each lateral tooth at base of rostrum, other long hairs fringe the margins of the rostrum, and there are a few scattered hairs on the carapace and abdomen.

Fig. 1. Left cheliped.
Fig. 2. Right cheliped.

Eyes short, well pigmented.

The first pair of chelipeds large, longer than abdomen, the left slightly larger than the right, propod in each compressed, with numerous hairs on the upper margin and a well-marked fringe on the lower margin just above a slight ridge which extends almost to the end of the fixed finger, rest of surface smooth; both fingers sharply pointed; movable finger

without definite teeth; fixed finger with 2 small teeth, one near the base and the other, slightly larger, about the middle of the inner margin; on the right cheliped sometimes a third tooth nearer the apex of fixed finger.

Length of carapace in largest specimen, including rostrum, 17 mm.; length of abdomen to end of telson, 29 mm.

Several specimens from Meyer Island and Coral Bay; others from, rock-pools at Sunday Island, collected by Captain Bollons.

I am unable to identify this species with any descriptions known to me, and therefore describe it provisionally as new; it may, however, prove to be identical with some of the species of Axius already described. I am a little uncertain if it is properly placed in Iconaxiopsis, but it seems to agree well with Alcock's description of this genus.
