part 2] PEECILACIAL FLOEAS FEOM CASTLE EDEN. 115- 



CYPERACE.E. 



Cxpeeus sp. 1. (PI. VII, fig. 8.) 



Nut small, broadly oval, triangular in section, truncate at trie- 

 base, not stipitate ; style short ; surface showing small hexagonal 

 pits, and beneath these tine, beaded, longitudinal striations. 



Length = '7 mm. ; breadth = '5 mm. 



In 1910 there were figured from Tegelen two species of Cyperas.. 

 One (op. cit. sp. 1, fig. 19) is very close to this Castle-Eden species 

 in size and in the character of its sculpture, but it is a little 

 broader. 



Both show one characteristic that is rare in Gyperus : they are 

 not stipitate. This marks them as not belonging to any European 

 species. Both at Tegelen and at Castle Eden the nuts were- 

 abundant. 



Cypeeus sp. 2. (PI. VII, fig. 9.) 



Nut broadly oval, triangular, scarcely truncate at the base, not 

 stipitate ; style short ; surface shining, shoAving the remains of 

 large hexagonal pits, and beneath these coarse, beaded, longitudinal 

 striations. Seven specimens. 



Length = l - 2 mm.; breadth = - 75 mm. 



This species is distinguishable from the last by its greater size- 

 and its bolder striations. Like the last it is not stipitate, and does, 

 not belong to any European species. In size and shape it is very 

 similar to G. pilosus Yahl, which also is not stipitate, a native of 

 the tropics of the Old World. 



SCIEPUS Sp. 1 (qf. S. TABEEN^EMONTANl). (PL VII, fig. 10.) 



This broken nut in its general shape and cell-structure resembles. 

 S. taberncemontaui, but it appears to have been narrower and 

 smaller than any specimens of this species that I have seen. It 

 is probably a variety. 



Length (incomplete) = 2 mm. ; breadth (incomplete) = 1 mm. 



Sciepus sp. 2. (PI. VII, fig. 11.) 



Nut regularly oval, plano-convex, not stipitate ; style short ; 

 finely pitted with cells having a central boss ; one nut shows, 

 a broad bristle or stamen. 



Length = P5 mm. ; breadth = 1 mm. 



Sciepus sp. 3. (PI. VII, fig. 12.) 



Nut oval, flat, rather soft, not stipitate ; style veiy short, 

 surface of quadrate cells with central boss ; showing near the base 

 a ring of depressions, which probably corresponds to the position, 

 of attachment of the bristles or stamens. 



Length=l"3 mm. ; breadth='7 mm.
