Here, as in the Terra Nova Report, I regard murrayi as a perfectly distinct species. Chilton's (1912) and Schellenberg's (1926) records therefore do not apply; and in the Terra Nova Report the reference to Schellen- berg and the Gauss locality should be deleted. It is curious that this species was only taken once by the ' Discovery.' Distribution. Ross Sea. Tryphosa triangularis, (Fig. 16). Occurrence: 1. St. 140. South Georgia. 1 c?, 1 immat. $ 9
