median tubercle. A little behind the centre of the carapace is a nearly 

 straight transverse row of three tubercles, and in advance of these a 

 pair. The margins are diversified by a concavity behind the orbits, 

 followed by an oblique .line, beyond which the carapace rather abruptly 

 widens with a broad curve gradually sloping to the posterior lobes ; the 

 margin almost throughout finely granular or denticulate. The pleon 

 has a narrowly triangular telsou, fully twice as long as the small sixth 

 segment, which has a roughened surface ; the three preceding segments 

 consolidated, but widening successively forward in a conspicuous 

 manner. The character of the male appendage is shown m the 

 figures. That which appears remarkable in this species and in Nursia 

 scandens is that the vibratory lamina of the second maxilla is quite 

 devoid of the customary fringe of setae (notably developed in Eumiersia 

 ensifer, S. I. Smith, see ' Bull. Mus. Comp. Zool./ vol. 10, No. 1, p. 78, 

 pi. 13, fig. 4, 1882, and in MicroprostJiema crassimamis, Richters, see 

 Balss, ' Dec. rot. Meeres,' p. 34, fig. 27, 1915). Like the first and second 

 maxillipeds this maxilla is remarkably delicate, and the specific name 

 is an appeal for further light on these organs in other members of the 

 family. Characters of the carapace make me doubtful as to whether 

 I am justified in allotting the species here described to the genus 

 Nursia.

The new species, named after Prof. J. R. Henderson, who instituted 

 the genus, is distinguished from the type species, E.frontalis, by the 

 character of the front, by the absence of the " prominent blunt spine " 

 from the lateral borders, by the comparative robustness of the 

 chelipeds with differing details, and by differences in the small fourth
