(As preserved in formalin) dark crimson- maroon dorsally, more crimson ventrally, sternum pale but speckled; carapace with 3 broad longitudinal pale, dark-bordered stripes, a pair of dark rings between the gastric-cardiac regions ending posteriorly in a pair of small shallow glabrous pits; abdomen with transverse crimson and pale bands; legs with pale stripes; chelipeds with pale stripe on hinder margin of 4th and 5th joints, hand with faint pale stripe along inner (upper) margin continued along finger, a more conspicuous pale stripe along middle of upper surface, con- tinued along cutting-edge of finger. Ortmann gave the. ground-colour as dark violet, paler below, with pattern as in the present specimens, but without mentioning the dark rings which are shown in Paulson' figure. Locality. Delagoa Bay. 2 specimens. () Distribution. Red Sea, Dar-es-Salaam, Zanzibar. d. Fig. 2i. Petrolisthes virgatus Paulson, a. carapace, denuded, the spinate setae shown only around the margin, b. ventral view of basal joint of left ant. 1. c. ventral view of peduncle of left ant. 2, with spinate seta further enlarged, d. spine-seta from front margin of hand of cheliped. Remarks. There can be little doubt that Ortmann's species is the same as Paulson's. From the figure (x 2) Ortmann's specimens measured 10 X 7-5 mm. but the length has almost certainly been exaggerated in relation to the width. Paulson's much better figure ( X 3) gives the size as (approx.) 6-17 X 5-7 mm. Fam. Sergestidae Gen. Acetes M. Edw. 1950. Barnard, loc. cit., p. 822 Key to the South African species 1.
