There are three distinct forms of what may prove to be the 

 same species : I*li<iloe ninonia, Druce, with the markiii^a 

 white ; I'haloe cottu, Druce, with the markings pale yellow; 

 and Phaloe levisi, with the marki!ip;s greenisli yellow. 



Named after Mr. Lewis, of El Sitio.

Papuina antiqua. Ad. & live. 



Additional material from Muswar Island includes specimens 

 which confirm the synonymy given in my former paper*; it 

 consists of white and of uniform pale yellow specimens, the 

 number of whorls varying from 4J to 5f^. In the description 

 of 1\ horderi, Sowb., it is said to have 6 whorls, but after 

 having examined the type specimen in the British Museum, 

 I find it should really be 5^, agreeing with the figure. 



Tiie following measurements will give some idea of the 

 variation in size and form of this species: —

Further specimens show that this species is excessively 

 variable in form, as the following measurements demon- 

 strate : —

Two varieties are worthy of note : in one the colour-band 

 is almost or entirely lacking; the other is typical in form and 

 coloration, but is thinner, and the interior of the aperture is 

 strongly granular, perhaps the result of some disease sutTcred 

 by the mollusc.
