CALLIOPIIDAE IS9 



segments 1-3, and a more faintly marked one on segment 4 also. Telson nearly twice as 

 long as broad, cleft nearly to half-way, each lobe with broadly rounded apex. 



Antenna 1 extending to end of pleon segment 3 in <S, shorter in ?, fiagellum calceo- 

 liferous, no accessory fiagellum. Antenna 2 extending to end of uropods in <$, shorter 

 in $, fiagellum calceoliferous. Epistome with a median keel, rounded in profile. Upper 

 lip with low transverse ridge, margin rounded. Lower lip with rudimentary inner 

 lobes. Other mouth-parts as in incisus. Inner lobe of maxilla 1 has two setae on inner 

 apex (cf. Stebbing's figure on pi. cxxxv). Palp of mandible stout, 2nd joint angular on 

 inner margin near base, 3rd joint falcate. 



Gnathopods 1 and 2 similar to those of incisus, but the palm more oblique. Peraeopods 

 1 and 2 as in incisus, with a similar but narrower and sharper process on middle of 

 anterior margin of 2nd joint. In the ? these processes are broader than in the S, and 

 are slightly serrulate on lower margin. Peraeopods 3-5 also similar to those of incisus, 

 but the hind margin of 2nd joint is excavate to a much greater extent, margin entire, 

 postero-inferior angle quadrate. 



Uropods as in incisus. Branchial lamellae simple, oostegites large. 



Remarks. As preserved both specimens are pale yellowish, with brown eyes; the 

 eggs orange. 



Genus Halirages, Boeck. 

 Stebbing, 1906, p. 290. 

 Schellenberg, 1929 a, p. 275. 



Schellenberg has shown that Bovallia regis, Stebb., should be transferred to this genus.

Occurrence: 1. St. 53. Falklands. 1 ovig. $ 13 mm. 



2. St. 55. Falklands. 1911-5 mm. 



3. St. 56. Falklands. 1 $ 11 mm., 2 ?? 21 mm. 



Remarks. The integument is covered with minute scattered punctae, and in some 

 lights, especially when the specimens are semi-dried, the appearance of markings re- 

 sembling, as Bate says, a flying bird is seen. 



The antero-lateral angle of the head is acutely produced in no. 3 , but quadrate in nos. 1 

 and 2. The eye varies both in size and shape, being either round or horizontally oval, 

 always with a pale margin. In the $ the ocular pigment forms an irregular strip along 

 the anterior margin of the head on the right side, but on the left side there is no trace 

 of an eye at all. 



The 1st antennae are usually shorter than the 2nd, but may be subequal. Filamentous 

 sensory setae on about every third joint in antenna 2 in both sexes. Inner lobes of lower 

 lip indicated only by a row of setae (cf. Stebbing, 1888, pi. lxxiii). The plumose setae 

 on the margin of the inner lobe of maxilla 1 vary from 4 to 7.
