86 THE NAUTILUS. 



Mr. A. DaCosta Gomez has called our attention to several New 

 Caledonian examples of Cyprcea tigris L. in his collection which 

 show a rostration like the New Caledonian forms mentioned above, 

 together with others diversely modified ; and as such forms have not, 

 to our knowledge, been noticed in this species, we have figured four 

 of them on plates vii and viii, the two plates representing different 

 views of the same specimens. 



I. The upper left hand figures show a shell having a broad chest- 

 nut dorsal streak, the rest of the back being clouded with chestnut, 

 light blue and dull pale brown. On the margins may be seen the 

 characteristic dappled coloring of tigris. The base is normally col- 

 ored. At the anterior end there are large callous lumps. The 

 posterior end is also a little produced. Length 83 mm. 



II. Upper right figures. This shell is broad and very heavy 

 (weighing 7| ounces). The dorsal streak is interrupted, chestnut, 

 partially overlaid with bluish callus. Elsewhere it is a soiled cream- 

 white, obscurely and irregularly mottled. The base is stained with 

 yellow around the mouth. The sides are very heavily calloused and 

 lumpy. Length 90 mm. 



III. Lower left figures. This shell is heavily calloused and pro- 

 duced at the ends and on the right margin. The spotted tigris 

 pattern appears on the other side, but is covered by a dark enamel 

 in the middle of the back. Base white, with some yellowish suf- 

 fusion in places. Length 98 mm. This shell is characteristically 

 New Caledonian in appearance. 



IV. Lower right figures. A broad form, heavily calloused at the 

 sides. The dorsal streak is dark purplish-brown; remainder of the 

 back bluisli-white, irregularly mottled and spotted with orange-brown 

 and purple-brown, ends blackish. Tlie base and teeth are brownish- 

 yellow except for a pure white area on the inner lip. Length 85 mm.
