108 CONCHOLOGICAL NOTES. 



Tiie specimens are exhibited in one of the table 

 cases in the Hastings Museum. There is little doubt that 

 the arrangement in which they now appear was not 

 intended as final ; additions would have necessitated 

 various alterations of positions. Among the additions 

 intended were univalve shells in sections, showing such 

 features as the columella, the sutures, the whorls, the 

 inner and outer lips, and also the anterior and posterior 

 canals. One such specimen is illustrated in plate XII. 

 It is exhibited in the same case as the other descriptive 

 shells. 



The anatomy of molluscan animals was also receiving 

 treatment, two creatures having been mounted in 

 preservative fluid in glass museum jars. The animals 

 producing bivalve shells are represented by the animal of 

 Anodontacygnea, Linnseus, the fresh- water Mussel, deprived 

 of its valves, and so displayed as to show the mantle, 

 mouth, foot, gills, and other organs, in an interesting and 

 instructive manner. 



The other specimen is the animal of Buccinium 

 undatum, Linnseus, the Common Whelk, illustrative of the 

 univalve group. It has been most cleverly treated 

 and arranged. Deprived of life while in the act of 

 crawling, various portions of the body the proboscis, 

 syphon, tentacles, etc. are fully displayed in a very 

 natural manner, allowing the anatomy of the creature to 

 be easily observed and studied. 



Upon the exterior of the jars small labels are affixed, 

 each label having a slender prolongation, terminating at 

 the part named. 



It has been thought that these, as also the series of 

 shells, on account of the educational value of both, are 

 worthy of reproduction in the present work. 



The circular shape of the jars, unfortunately, 

 detracts somewhat from the distinctness of the objects and 

 the lettering.
