Thomson. — Recent Brachiopoda of New Zealand. 



409 



rocks (Wanganuian) of the North Island, but has not hitherto been found 

 Recent. The specimen here figured was obtained by Captain Bollons from 

 Farewell Spit. The colour is pinkish- 

 red, as in N. lenticularis, and the shell 

 is sufficiently translucent for the pallia 1 

 sinuses to show through. 



It is rather remarkable that Neothyris 

 campbellica Filhol, which is intermediate 

 in characters between N. oralis and 

 N. lenticularis, should not also be found 

 Recent. It is a common Wanganuian 

 fossil in the North Island and on Camp- 

 bell Island.

Terebratella sp. cf. Magella carinata Thomson. 



In Mr. Hamilton's collection there are four specimens from Foveaux 

 Strait of a new species of Terebratella, which differ from T. rubicunda by the 

 possession of a more pronounced ventral unicarination, of an incomplete 

 foramen, and of distinctive colour-markings. The shell is of a pale pinkish- 

 white colour, with irregular radial splashing of deep red. Such colour- 

 markings are rare amongst Recent Brachiopods, but occur in Bouchardia 

 rosea. In shape the adult shells agree nearly with Magella carinata, but the 

 loop has advanced to an early Terebratelliform stage. The four specimens 

 comprise two adults, about the size of small specimens of T. rubicunda, 

 and two half-grown shells, not so carinate, and with Magaselliform septa. 

 Unfortunately, the two adults are too damaged to serve as type specimens, 

 and in consequence it is better to leave the species unnamed at present. 



It is remarkable that this species, undoubtedly a descendant of the 

 Oamaruian Magella carinata, should not be found in the Wanganuian rocks. 

 The explanation may be that it has always been restricted to a southern 

 habitat. Magella carinata has only been found near Oamaru. and the 

 present species occurs in Foveaux Strait, still farther south, while no 

 Wanganuian marine rocks are known from Otago or South Canterbury. 



Magellania flavescens (Lamarck). 



There is in Miss M. Mestayer's collection a single specimen of this 

 species, which probably comes from the Chatham Islands. It was in a box 

 of Hemithyris nigricans labelled "Chatham Islands and Lyall Bay," and, 

 since the Lyall Bay habitat has not been confirmed, the probability is that 

 it came from the Chatham Islands. Miss Mestayer is positive that it did 

 not come from Australia. Nevertheless, its occurrence must be verified 

 before it can be added to our list. 



The shell is a rather elongate form, with strong ventral uniplication 

 and little sign of Implication, and the multicostation is perhaps a little finer 

 than usual. Nevertheless, it comes well within the range of variation 

 figured by Davidson.
