GASTROPODA. 25 



Locality. — Rare at Minbu, 

 . Remarks. — It is unfortunate that the type specimen described 

 by Sowerby is so ill-preserved that it is most difficult to arrive at a 

 final decision from the figure only ; the general appearance is, 

 however such, that I do not doubt that the specimens from Burma 

 must be referred to this species. Their identity with those de- 

 scribed by d'Archiac and Haime is less doubtful, although they are 

 considerably smaller than those. Why d'Archiac considered fig. 18, 

 which either belongs to the genus Rostellaria or Aporrhais } as 

 identical with figs. 20 and 21, must remain an open question. At the 

 first glance the difference of the form represented by fig. 18 from figs. 

 20 and 21 is so striking, that it is difficult to understand why 

 d'Archiac should have considered thern as identical; the difference 

 must have been noticed by the author himself, because in the 

 description he especially mentions that he considers fig. 18 as a 

 variety only. 



In conclusion I want to draw the attention to the close resemblance 

 of Strombus nodosus> Sow., in its type from Burma to Strombus 

 coronatus, Def., particularly to those forms as figured by Hoernes x ; 

 the resemblance is so striking that I rather feel inclined to think 

 the specimens from Burma identical with that form, but I refrained 

 from doing so on account of their mutilated shape which did not 

 permit a decisive opinion. I think, however, that this is highly pro- 

 bable but only actual comparison of better preserved specimens will 

 decide this question ; in the meantime the name of Strombus corona- 

 tus t Sow., may be retained for the Indian and Burmese varieties.
