present species having nearly two glossy, horn-colored whorls 

 with a carnia running about their base, while ternispina has an 

 apex with two and a half conical, glossy, smooth whorls. 

 The species is found in China and Japan.

This is a species which is rare in collections, and therefore 

 but little understood. I have received it under various names 

 but it is more often confounded with ternispina. I recently 

 had the pleasure of examining over a dozen specimens fresh 

 from Japan. It is a perfect giant, being the largest of the 

 subgenus. The spines are short and blunt, and almost 

 straight, resembling in this respect Martinianus. There are 

 no intervarical nodes on the last three whorls, but on the first 

 three, after the nuclear whorls, there are four well-devel- 

 oped costae; there are on the body-whorl five to seven strong 

 spiral lines of a rich red color, and between these larger lines 

 several finer lines. The operculum differs also, being nearly 

 round, and having its surface raised in strong lines of growth. 

 That of ternispina is long-ovate and the lines of growth are 

 not nearly so prominent. The nuclear whorls are widely 

 different, those of Troscheli having a very strong, sharp carina 

 encircling two and a half whorls, while in ternispina there 

 are but one and one-half rounded whorls destitute of a carina. 

 The largest specimen examined measured as follows: Alt., 6.8 

 in.; diam., 2.10 in.; aperture alt., 1.25 in. ; diam., 0.75 in. 

 It has been reported from Japanese waters only. 



MuREX Cabritii Bernardi.

This is a rare species in collections and I was quite sur- 

 prised to find two very perfect examples in a lot of shells 

 recently examined. Its principal distinguishing point is the 

 row (4) of long spines on the canal; all the other spines are 

 very short. The color is pink or pinkish-white. There are 

 three distinct longitudinal costae, and numerous distinct spiral 

 lines encircling the body whorl. The species is not likely to
