REPORT on THE CIRRIPEDIA. 119 



ridge runs towards the posterior basal angle. This ridge divides the valve into a larger 

 lateral and a smaller rostral part. 



Infra-median latins extremely narrow, with the unil car the base ; the part above 



the umbo is comparatively large and wedge-shaped, the part below the umbo is small 

 and triangular. 



Carinal lotus quadrangular, with the umbo projecting considerably beyond the 

 carina. The carinal margin is hollowed out, the upper and lateral margins are straight. 

 The basal margin is rather long, the lowest parts of the carinal margins of the two carinal 

 latera touch one another under the middle of the carina. From the umbo a curved ridge 

 runs to the anterior basal angle of the valve. 



Length of the capitulum, 12 "5 mm. 



Peduncle slightly conical, being a little wider near the capitulum than near 

 the base. It is very short (little more than 2 mm. long). The scales are prominent 

 and not numerous, each longitudinal row contains no more than seven, and there are 

 five of these rows. The scales near the capitulum are distinctly larger than those near 

 the base of the peduncle. 



Of this beautiful little species I have not studied the internal structure of the animal, 

 nor have I been able to observe the complemental male. 



The species was dredged at Station 184, August 29, 1874; kit. 12° 8' S., long. 145° 

 10' E. ; depth, 1400 fathoms ; bottom temperature, 1°'8 C. ; bottom, grey ooze. 



Observations. — Scalpellum austraHcum is nearly related to Sealpellum antarcticum, 

 Sealpellum tome, and some other species. Future investigators examining a great number 

 of specimens, will perhaps only regard as varieties what I believe to be distinct species. 



Scalpellum temie, n. sp. (PI. IV. figs. 20, 21 ; PI. X. fig. (5). 



Valves thirteen, covered by a thin woolly membrane. Carina, with the umbo at the 

 apex, simply and feebly bowed, with the roof flat. Upper latus trapeziform. Infra- 

 median latus narrow, small. Umbo of the carinal latus not projecting beyond the carina. 

 Peduncle cylindrical, short. 



This species is represented by a single specimen only ; in general shape it much 

 resembles Sealpellum antaretieum. On closer examination it appeals to be distinct. 



Capitulum consists of thirteen valves ; there is a trace of a rostrum, but it is too 

 rudimentary to be considered as a distinct valve. The valves are covered by a thin 

 woolly membrane; the lines of growth can only be followed indistinctly under that 

 membrane. In general outline the valve is elongate-oval; at its base it is sharply 

 marked off from the peduncle. 



Scutum about twice as long as broad. Occludent and lateral margins nearly parallel ;
