2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. lO/ 



Many varieties of Liguus are now living in hammocks far outside 

 of their original ranges, having been carried thence by collectors 

 desirous, perhaps, of saving a choice race. As a result, distribution 

 records made within the last few years mean relatively little; but 

 Dr. Simpson's data, collected before this widespread transplanting 

 had begun, gave him an excellent conception of variation, relation- 

 ship, distribution, and sources of stock. 



During the years Dr. Simpson spent in the study of Liguus, he 

 recognized as new i8 varieties to which he assigned names. Of 

 these, i6 are now generally accepted as valid forms. He likewise 

 noticed, but did not name, the form subsequently called splendidus 

 by Frampton, referring to it as the "form . , . ." which ". . . . has 

 broad, brown, zigzag stripes." 



Certain discrepancies have been noted between the measurements 

 given in the original descriptions and those published in 1929, and 

 it was therefore considered advisable to remeasure the types, with 

 regard to a high degree of accuracy. This has been done, using 

 vernier type calipers, and the resulting dimensions are given in this 

 paper. The careful observer also will note certain discrepancies with 

 respect to the specimen figured as "the type" in a few cases, and the 

 question might easily arise as to just what specimen the type might 

 be. However, by careful examination of the figures and descriptions, 

 and comparison of specimens, the identity of each type has been 

 established in all cases except one {crassus) that seems to be lost. 

 In each instance, the final decision coincides with those labeled "type" 

 in Dr. Simpson's own hand. 



Some of the types are figured in a popular account of south 

 Florida ^ published in 1920. Others are illustrated in the 1929 mono- 

 graph, while one, Liguus fasciatus castaneus, has not been pre- 

 viously shown, neither of the specimens figured in the monograph 

 being the type. 



Since the figures of the types are located in volumes now prac- 

 tically unobtainable, we have gathered them together on one plate, 

 with the hope that they will be of interest to students of the genus. 



It is also desirable to confirm the presence of these types in the 

 Biological Museum of the University of Miami. It is very gratifying 

 to know that they are at last in a place of safety, and have suffered 

 only one loss.
