AbstractIn 1898 Borradaile described a new species of Coralliocaris from Funafuti, Ellice Islands. The original diagnosis was very short, but one year later Borradaile (1899: 1006, pl. 64 fig. 7) gave a slightly longer description and illustrations. No new finds of the species have been reported upon since then. In the collection of the Zoologische Sammlung des Bayerischen Staates in Münich 3 specimens of the species were found. As Borradaile's descriptions are short, this opportunity is taken to provide a more detailed account of this characteristic species.
I wish to express my thanks to Drs. W. Engelhardt and H. Fechter of the Münich Museum for entrusting me with the study of this material.

The rostrum is depressed, unarmed and curved down. It reaches to the base or to the end of the second segment of the antennular peduncle. In dorsal view it is triangular, with a rather wide base and slender distal part.
The distal portion is much narrower than shown in Borradaile's figure. Both the dorsal and the ventral surfaces of the rostrum bear a sharp median carina. The lateral margin of the rostrum continues backwards and ventrally as a postorbital carina and then switches anteriorly to end in the antennal
