defect specimens and one young of indefinite sex, meas- 

 uring 30 mm. were taken. 



The largest specimen, a female with a carapace 104 

 mm. long measured 334 mm. from tip of telson to tip of 

 rostrum. The species has been taken on both sides of 

 the Atlantic, in the Gulf of Bengal and in the Andaman 

 Sea but not in the Mediterranean. Bathymetrical limits 

 344 to 1850 metres.

Aristeopsis tridens S. I. Smith.

This large prawn was obtained on two occasions 

 during the expedition, both of the catches within the 

 bathymetrical and horizontal limits of distribution as 

 previously known, viz: 



at st. 35, trawl, 2603 metres, 5 males and 3 females, 

 at st. 53, trawl, 2615—2865 metres, 21 males and 20 

 females. 



The sizes of the specimens were as follows:

The total length is about 4 times that of the cara- 

 pace measured from the orbital sinus. 



As the species is perfectly well established by Smith 

 (1884) and clearly distinguishable from A. armatus (Bouvier 

 1909), there seems to be little reason to encumber its 

 name by referring it as a variety of another distinct though 

 nearly related species.

This species was taken together with Parapenceus 

 longirostris, at st. 21, trawl, 535 metres. 



Two females, length of carapace 58 and 65 mm. 

 respectively. 



The species is known from the Mediterranean and off 

 Morocco in depths between 500 and 1300 metres.
