 pi. iii., fig. 4 : Faxon, Mem. Mus. Comp. Zool., Vol. XVIII , pp. 164-167, pi. xliii., 

 figs. 2-5. 



In fonr small specimens obtained this year, the largest of which is 

 an ovigerous female 36 millims. in length, the tooth on the antero- 

 inferior margin of the laminar part' of the rostrum is absent. 



At the distal end of the dorsal surface of the carpus of the 1st 

 pereiopods is a small blunt recurved tubercle, and, leading to it, an oblique 

 line of short stout hairs on the inner surface of the palms of the same 

 pair of legs. 



Both margins of the inner, and the inner margin of the outer, plate 

 of the swimmeret are minutely serrate. 



Stations 198 and 203 ; 764 and 364 fms. 



21. Acanthephyra cristata, Faxon. 



Faxon, Bull. Mus. Comp. Zool., XXIV., 206, 1893 ; Memoirs Mus. Comp. Zool.,

 gator,' Crustacea, pt. iv., pi. xxv., figs. 2, 2a. 



The end of the telson, which was wanting in both Faxon's speci- 

 mens, is prolonged into a sharp spine armed on both sides with movable 

 teeth, of which one on each side at a little distance from the tip is 

 specially large and strong. Both margins of the inner and the inner 

 margin of the outer plate of the swimmeret are minutely serrate and 

 clothed with long silky hairs. 



Colour in life, dark crimson. 



Length from tip of rostrum to end of telson 67"5 millims. 



Station 183 ; 890 fms.

 Anderson, J. A. S. B., Vol. LXIIL, pt. ii., 1894, p. 157. 



Several specimens from stations 201 and 203 ; 320-296 and 364 

 fms. When placed in a tub of water tbey swam about with great 

 vigour, but were unable to maintain an upright position, always turning 

 over on one side. They would appear, as previously mentioned, to live 

 at no great depth, as the specimens of Lyreidits, Ethusa, TJroptychus 

 and Nephropsis, all bottom dwellers, which were captured at the same 

 stations as the Hoplophorus, were quite dead on reaching the surface. 



Colour in life bright transparent red with golden coloured glisten-
