sheaths ; lower rather broad, leafy, often overtopping the 

 spikes ; second long, setaceous ; the rest small, short. Spikes 

 lax below, scarcely an inch long. Glumes oblong, blunt, pur- 

 phsh brown with a broad green band up the midrib, at least 

 one-third shorter than the fruit; on the barren spike paler 

 and obovate-lanceolate. Perigone nearly twice as long as the 

 nut, gradually narrowing from below the middle to the top, 

 pale green, with numerous and rather strongly marked ribs, 

 which do not extend to the apex ; beak very short, truncate, 

 entire. Nut compressed, rather longer than broad, widening 

 upwards, rounded above, \\-ith a short somewhat conical beak, 

 from which the style is deciduous, pale brown, opake. 



Found at Wood Hey near Hebden Bridge, Yorkshire, in 

 1840, by Mr. S. Gibson of that place : flowering in June. 



In C. Goodenovii (C. caespitosa, Gooden., Sm.) the fruit is 

 elliptical and very slightly longer than the glumes, the nut 

 roundish and rather broader than long, the glumes purple 

 with a slender pale green keel. 



Tn C caspitosa (C. stricta, Gooden., Sm.) the fruit is elliptic-

This fish was taken with a hook off Norfolk Island on 

 Cook's second voyage. It differs from the other Seriolce de- 

 scribed in the ' Histoire des Poissons' in the extremely acute 

 under surface of the head, in the first dorsal being continuous 

 with the second, though lower, and in other particulars. We 

 must refer to Schneider for J. R. Forster's account of it, but 

 it is to be regretted that he does not state whether the vomer 

 and palate-bones are toothed or not. The following particu- 

 lars are drawn from an inspection of George Forster's figure. 

 The pectoral fins are small and somewhat falcate. The ventrals 

 are also small, and are attached by their internal borders to the belly.
