WATSON : MARINE MOLLUSCA OF MADEIRA. 37 1 



Museum. I think he must hastily have taken for it a very 

 young and perhaps not very well preserved specimen of Thracia 

 pubescens^ which in that condition somewhat resembles it. 



Pectimculus siculus — It is very remarkable that this species 

 which McAndrew marks 'frequent' should have entirely escaped 

 all but McAndrew. Both in the British Museum and at Cam- 

 bridge several specimens of this species are marked as from the 

 Canaries, but there are none from Madeira, so that the name 

 has probably crept in by mistake. 



Murex cristatus, 'rare.' There are no specimens of this 

 species from Madeira in either of the museums. One of the 

 new species found by Mr. Lowe and also by myself at Madeira 

 so far resembles M. cristatus Broc. that Dr. Gwyn Jeffreys, to 

 whom I sent it in 1870, wrote that it might possibly be M. 

 cristatus Broc, but that he was not quite satisfied, and better 

 specimens made it obvious that they were distinct. It is this 

 new species, therefore, which most probably misled Mr. 

 McAndrew. 



Amphispira hyalina.—-' OnQ.' From Madeira, distinctly, 

 there is no specimen of this species in either museum, but in 

 the Cambridge collection there is a card bearing two specimens, 

 and on it Mr. McAndrew has written ' Canaries and Madeira '; 

 but in his own (1854) copy of his report he has (under Madeira, 

 p. 41) opposite to the entry 'one specimen' written 'broken, 

 destroyed.' At the same time on p. 34 of his own copy, where he 

 states that the species is 'rare' at Ortava in the Canaries, he has 

 noted that he got only 'one' specimen. In these circumstances 

 it is impossible to read any further the history of the two speci- 

 mens in the Cambridge Museum, but until some other speci- 

 mens be found the species can hardly remain in the Madeira 

 list. 



Excluding, then, these four, 115 remain, of which I may 

 refer here to two. 



Buccinum minus 'rare.' No specimens from Madeira of 

 this species are in either museum, but in the Cambridge collec-
