constant characters to distinguish tliem, and have been able to 

 bridge over all the gaps between the extremes of variation by 

 serial specimens. Thus the main features of difference between 

 T. waterhousei and T. spengleri, drawn attention to in the 

 original description of the former by Messrs. Adams and Angas 

 are that T. waterhousei has a scjuamato-pilose epidermis, a broad 

 flattened varix to the outer lip, double line on the whorls, and a 

 smooth inner lip anteriorly. Although specimens of this type 

 can be obtained, still with the inteiinediate forms, we have been 

 compelled to regard them as the same species. T. barthelemyi, 

 Bernardi, appears to us to be but one of the senile types of 

 T. spengleri, and we have no hesitation whatever in including it 

 as a synonym. T. strangei, Adams and Angas, is also a synonym, 

 having been founded upon a young specimen with a perfect and 

 characteristic embryo ; this portion of the larger and more adult 

 specimens being almost always diti'erent in appearance on account 

 of erosion or corrosion.

Obs. — The habitat of this species is given by Reeve on the 

 authority of Cuming as Island uf Ticao, Phillipines ; at the same 

 time, however, he mentions that the shell has somewhat the 

 form of the New Holland species T. Quoyi. With the latter
