Thompson.— Metamorphoses of Hermit Crab. 
PLATE 8. 
Development of the livers. 
All the figures are schematic, but each represents the condition in a single 
individual, depicted either from a “plotting ” on profile paper, or from a wax 
reconstruction. Allowance must be made for shrinkage and shiftings in the 
loosely attached organs, especially in figure 84-37, and 44. Figure 34-37 are 
drawn in relative proportions ; figure 38-42 with a common length of thorax. 
The slender liver caeca are crowded together in the living animal, but sepa¬ 
rated here for clearness.
