is also the pattern occurring in Cozumel I -land, win-re one -pecimen 

 (pi. .-j.s, tig. s;{) was collected in is'.UI l,y Dr. C. F. Millspaugh dur- 

 ing the West Indian cruise of the yacht " I'towana." It wa- found 

 on the trunk of a low Sabal palm about two feet from the ground, 

 ami about 500 feet from the beach. 



It does not seem to nn- de-irable to apply names to the numerous 

 form* of L. fasciatu* until they are far better understood than at 

 present ; but a synopsis of the main variations may be useful. 



n nineties. 



Typical form. Solid and strong, the columella more or less 

 truncate ; white with a broad belt varying Iroui purplish- 

 pink to bluish above and another below the white peripheral 

 band, \\hich is usually divided by a brown line; the colored 

 belts generally with greenish lines and dark flames: spire 

 flammulate, with spiral lines at the sutures; coluniella and 

 apex pink or white; parietal callus often pink-edged (pi. 57, 

 figs. 70, 71 , 72). Cienfuegoe, etc. Through various tra:i-i- 

 tions this blends with form In. 



The Cd.iniiff hln<l !<>nn is somewhat similar to the above. 

 It is solid with distinctly truncated coluniella; with two wide 

 Macki-h bands, traversed by darker lines and somewhat 

 spotted with yellow, on a white ground becoming yellowish 

 below and pink near the apex, the band- gradually disappear- 

 ing on the latter halt of the la>t whorl, and replaced by 

 several greenish lines, (pi. .~iX, lig. s;}). 



In. Similiarly solid, large, the columella varying from 

 very >lroiigly to weakly truncate. White, often yel- 

 lo\\i.-h on the last whorl, with a brown line at the 

 periphery, and nmneroii- gra->-green or yellmvish- 

 green line.-, and narrow hand.-, and more or less 

 .-treaked or maculated with purpli.-h aho\ e ; parietal 

 callu- often with a dark chc.-tnut border, and xune 

 ,-igmoid streaks within (pi. .".7, lig-. 7.'i, 71). 

 Tran-ilion> toward- var. rn'mi/n occur. 



Mi. Similar to n, luit green line- wanting or faint (.1. /"//- 

 li'ilu Swain-., pi. ;Vs, lig. S2). The lack of green lines 

 is olten due to wear. The che.-lnnt -trcaks upon the 

 parietal callu> ai-e often con.-pienous. This form .-ome- 

 times attain- a length of 7n-7-"i mill.
