FOSSIL CIRRirEDES FROM NEW ZEALAND. 851 



Material. 6 carinse, 4 scuta, 2 terga, 1 upper latus, and 1 rostral 

 latus. 



Holotype. The carina, I. 15409 (fig. 8). 

 Collection. Brit. Mus. (Nat. Hist.). 



Horizon and Locality. Miocene, Upper Oamaruian. Blue 

 Clay : Pareora, South Canterbury, New Zealand. Limestone : 

 Takiroa, Oamaru District, N. Otago, New Zealand. 



In the Geological Department of the British Museum there is 

 a series of 14 valves of a species of Scalpellum {sens-u lato), 

 registered 1. 15409-1. 15422. Although these come from difi'erent 

 localities, they are of interest, since they appear to represent a 

 single new species and enable us to gain some idea of the form 

 of the capitulum (see restoration, fig. 13). 



Three of the valves (a carina, scutum, and rostral latus) are 

 labelled '■'■Scalpellum \ (IBlue Clay) | Parimoa, New Zealand | Mr. 

 C. Mantell." The reinaining eleven valves (5 carinte, 3 scuta, 

 2 terga, and 1 upper latus) are labelled '■^Scalpellum | Takiroa, New 

 Zealand | Mr. C. Mantell." With the latter series is a MS. label 

 (probably written by the collector) bearing the words "Lime- 

 stone I Takiroa-Crinoline Qu. 1852." 



It is fairly obvious that the " Mr. C. Mantell" was intended 

 for the late Hon. Walter Mantell, from whom a collection of 

 New Zealand fossils was obtained by the British Museum in 

 1856. On failing to trace the above-mentioned localities, I wrote 

 to Prof. James Park, who kindly informed me that " Parimoa " 

 should be Pareoi^a, South Canterbury, and Takiroa is in the 

 Oamaru District, N. Otago ; he was of the opinion that the 

 Cirripede valves came from beds of Miocene (Upper Oamaruian) 

 age. " Crinoline Qu." may mean Crinoline Quarry. 



Description of Valves. Valves thick, ornamented exteriorly 

 with numerous exceedingly fine ridges radiating from their 

 apices. 



Carina narrow, widening very gradually from the apex, 

 moderately bowed inwards, basal margin rounded. Tectum 

 almost flat transversely, not carinate. Parietes more than half 

 the width of the tectum (in one old specimen nearly as wide), 

 bent nearly at right angles to the tectum. Intraparietes very 

 narrow, bent abruptly inwards and meeting just below the apex, 

 so that a small portion of the valve projected freely. Umbo 

 apical. 



Length (fig. 7, incomplete valve) 19-2 mm. ; breadth 6"5 mm. 

 Length (fig. 8, small complete valve) 16 mm. ; breadth 3*7 mm. 

 Scutum trapezoidal, almost twice as long as wide ; basal and 

 lateral margins slightly concave, nearly at right angles to each 

 other ; tergo-lateral angle reaching a point a little above the 

 middle of the valve ; tergal margin straight and its outer edge 

 flat ; tergo-lateral portion of valve slightly concave ; occludent 

 margin moderately convex and very obliquely inclined towards 

 the terga. Umbo apical. 



Length (fig. 11) 27*4 mm. ; breadth 15 mm.
