THE NAUTILUS.

Solen americanus. 



ally abundant, many of tliem being per- 

 fect in form, and exhibiting in the aper- 

 tui-es the rarest shades of crimson, pur- 

 ple and orange. Excellent specimens of 

 Natica d'uplicata were also found here in 

 situ, these offering a new revelation 

 to the collector as he saw, when 

 lifting them from their beds, fine jets of 

 water spouting in every direction from 

 the edges of each large saucer-shaped 

 foot. Both of these species were carried 

 to the hotel and boiled — the former 

 about ten minutes the latter two or three 

 minutes. This made the removal of the 

 animals an easy matter, leaving the lus- 

 tre of the shells and color of the aper- 

 tures uninjured. It should be remem- 

 bered that the peninsula referred to is 

 only free from water when the tide is 

 nearing its lowest stage; also that the 

 tide is low there at about the same hour 

 it is high in Philadelphia. 



In conclusion it may be well to inform 

 the young collector that in the search for 

 sea shells at least three adjuncts are neces- 

 sary — a trowel for digging purposes, a 

 water-tightjar for preserving living speci- 

 mens and a good sized basket for large 

 shells. With these in hand, and a taste 

 for the work, there is no reason in the 

 world why he shouldn't be both success- 

 ful and happy.
