much wider than the intervals. Three spirals below the suture are 

 narrow. On the penult whorl there are five subequal wide spirals 

 besides three subsutural narrow ones, the intervals traversed by 

 fine threads. The last whorl has twenty wide and three narrow 

 spirals. The aperture is narrow. Lip having about the same 

 structure as in M. camura. There is a large parietal tooth, with 

 smaller ones above and below it, and a prominent, double, columellar 

 tooth ; the columella and the upper part of the parietal wall strongly 

 rugose. 



Length 53.5, diam. 34.7 mm.; 5f whorls remaining, the tip wanting. 



Type No. 2590. 



The very much less raised and more numerous spirals, as well as 

 the general shape of the shell, separate this from M. camura. 

 Malea goliath n. sp. 



Large and globose, thin, with sculpture of broad, flat spirals 

 parted by furrows from one-fourth to one-third as wide, 19 spirals 

 on the last whorl, five on the penult and next earlier, where the 

 median one is larger and prominent. Perietal tooth composed of 

 four plaits. Columellar prominence with about six plaits, the 

 upper three larger. Outer lip broken, but fragments indicate struc- 

 ture similar to M. camura. 



Length 129, diam. 107 mm. 



Type No. 2592. 



Strombus galliformis n. sp. 



Strombus bituberculatus Lam., in part, Gabb, Tr. Am. Philos. Soc, XV,

, Related to S. gallus L. The spire is high, with sculpture of axial 

 riblets and inconspicuous varices on the earlier whorls, changing 

 to short tubercles on the last four, the penult whorl having two 

 low, massive varices. Whorls of the spire having unequal spiral 

 striae. The last whorl has a smooth shoulder in front, three high 

 tubercles on the back, the central one largest; the whole surface 

 having widely spaced spiral ridges and fine, very weak, spiral striae. 

 Lip produced upward in an angle, smooth within; no entering wrin- 

 kles on the posterior end of columellar lip. 



Length 100, diam. 66 mm.; 9h whorls. 



In the recent S. gallus the lip is far more produced upward and it 

 spreads on the left side above the shoulder; the spiral ridges on the 

 back are coarser, and the tubercles at the shoulder more numerous. 

 The new form is more like S. peruvianus in form of the lip, but that 

 species has the throat conspicuously rugose. 



Type is No. 2582, A. N. S. P.
