bare at low water, but one individual was dredged at a depth of 

 two fathoms. 



There are tufts of setae on the carapace and abdomen of all 

 the specimens; the males are small and do not possess the enlarged 

 third maxillipedes and first peraeopods characteristic of well-grown 

 examples of their sex. 



On close inspection the colouration of living specimens is 

 very wonderful, resembling that of a rich Turke}^ carpet. At a 

 casual glance, however, the animal is dull in tone and it is clear 

 that the vivid tints blend and cause it to harmonise with its sur- 

 roundings, just in the same way that the splashes of bright colour 

 on gun-mountings are effective in rendering them inconspicuous. 



On the carapace and abdomen are numerous large ocellar 

 spots of an irregular shape ; in the centre these spots are bufii, 

 dotted with red and circumscribed with white and reddish orange. 

 Between the spots are patches, irregularly lobulate in form, but 

 symmetrical on either side of the animal. They are of a deep red- 

 dish brown colour with numerous large bright blue spots. Each 

 patch is sharply defined, its sinuous margin being outlined with 

 black and pale grey. At the antero-lateral angle of the carapace 

 there is a dull red spot. The rostrum, antennules and antennal 

 scales are pale bull', barred with dark brown, the brown bearing 

 numerous white flecks. The anterior two pairs of legs are reddish 

 at the base ; their distal segments and all segments of the last 

 three pairs are pale yellowish green broadly barred with black. 

 The tail-fan is obscurely mottled with brown and buflf. 



The largest specimen, an ovigerous female, is only 36 mm. in 

 total length.

A number of examples of this species were obtained by Dr 

 Annandale during his recent visit to Japan from Mr. Kuma Aoki. 

 The teeth on the rostrum vary from 8 to 10 on the upper border 

 and from 10 to 13 on the lower.

Two fine specimens in Dr. Annandale's Japanese collection 

 (presented by Dr. S. Yoshida) agree very closely with de Man's 

 description of the male of this species. Both individuals have 

 only 5 teeth on the upper border of the rostrum; on the lower
