1891.] BAKER— SHELLS FROM THE MAURITIUS. 27 



The specimens of this species are very large and fine, measuring 

 nearly two inches in length. The shells are a beautiful :flesh-color, and 

 the columellar callous spreads over a considerable portion of the shell. 

 They are much finer than any I have seen from any other locality. 



108. Nassa (Zeuxis) taenia. Quite common and very large. 



109. Nassa (Zeuxis) gaudiosa, Hinds. A species with 

 upwards of fifteen synonyms. 



110. Nassa (Zeuxis) punctata, A. Adams. Scarcely a syn- 

 onym of gaudiosa. The shell is much longer in the spire, smoother 

 and of a dark brown, almost black color, while gaudiosa is yellowish 

 with reddish markings. 



Family COLUMBELLIDiE. 



111. Columbella turturina, Lam. 



112. " (Conoidea) tringa, Lam., (=?///^/dr/«, Duclos.) 

 Both forms quite common. 



Family MURICIDiE. 



Sub-family Muricin.^. 



113. Murex (Pteronotus) triqueter, Born. Very common. 

 Usually received from Mauritius collectors under the name of 

 Cu7ntngii, A. Adams. 



114. Ocinebra pumila, A. Adams. This species has not been 

 heretofore reported from this region. It is a rare form, judging from 

 the limited number of specimens received. 



115. Ocinebra (Favartia) brevicula, So wb. Unusually large 

 and heavy. 



116. Trophon (Aspella) anceps, Lam. A common form. 

 This species has usually been considered a Ranella, but is more 

 properly placed in Trophon on account of its dentition. 



Sub-family Purpurin.e. 



117. Purpura Persica, Linn. 



118. lopas sertum, Brug. 



119. Vexilla vexillum, Chemn. These three forms were 

 received in considerable quantities.
