318 DR THOMAS SCOTT ON THE 



//,,/, /c,</. Amongst small shells and other things collected on the shores of the 

 Falkland Islands in Port Stanley by the S.Y. Scotia ; Station 118, 51 41' S., 57 51' W. 



Remarks. Perhaps the most noticeable difference between the present species and 



the two already described is the absence of the tooth-like process on the second joint 

 of the autennules. But there is also a slight difference in the form of the fifth pair 

 of thoracic legs of the female, as well as of the caudal rami. Named in compliment to 

 Mr MOSSMAN, meteorologist to the Expedition. 



Fam. LAOPHONTID^;. 



Genus Laophonte, Philippi, 1840. 



Laophonte rottenburgi, new species. (PL VII. figs. 1-6.) 



Female. Body narrow, elongated. Length, 1 mm. (^ of an inch). 



Antennules seven-jointed ; first three moderately stout and of nearly equal length ; the 

 fourth and fifth joints are short, while the next two are each about twice as long as the 

 fifth. The second joint is produced behind into a stout, blunt-pointed tooth (fig. 1). 



Antennae and mouth-organs somewhat similar to those of the next species. 



The first pair of thoracic legs are moderately stout ; the outer ramus is composed 

 of three subequal joints, and reaches to about the middle of the first joint of the inner 

 ramus. The inner ramus is tolerably elongated ; the first joint is long and narrow, and 

 bears seven or eight widely scattered hairs on the inner margin ; the terminal claw is 

 long and tolerably stout (fig. 3). In the next three pairs, the first joint of the inner 

 ramus is very short, but the second is moderately elongated. 



In the fifth pair, which are comparatively small, the proximal joint is of moderate 

 size and broadly subtriangular, and the distal end, which reaches beyond the middle 

 of the second joint, is obliquely truncated and furnished with about five setse ; the three 

 on the inner margin are set widely apart, while the two at the outer distal angle of the 

 joint are moderately close together, with a considerable space between them and the 

 nearest of the other three ; the second joint is broadly ovate, transversely truncated 

 at the end, and furnished with four setse on the truncated margin and two on the 

 outer margin, as shown in the drawing (fig. 5). 



Caudal rami short. 



Habitat. South Orkney Islands, in siftings from some dredged material collected 

 in June 1903 ; Station 325, 60 43' 42" S., 44 38' 33" W. 



Remarks. This species is easily distinguished from the other species of Laophonte. 

 described here by the structure of the antennules and of the last pair of thoracic legs. 

 Named in compliment to Dr PAUL ROTTKNBUKG, a subscriber and one of the members 

 of Committee. 



Laophonte australis, new species. (PI. XL figs. 10-17.) 



Female. Body slender and elongated ; similar to Laophonte minuta, Boeck, in 

 genera] appearance. Length, 077 mm. (fig. 10).
