Dr. Leidy remarked that the honey was contained within the stomach, which, 
with the abdomen, was enormously distended, assuming a globular condition. 
The pergamentaceous segments are widely separated and appear as black bands 
upon the dorsal and ver:tral surfaces of the translucent abdomen. The thorax 
and head are about two lines long; the distended abdomen 44 lines in diameter. 
All the other viscera of the abdomen are completely obliterated, and even the 
tracheal vessels have entirely disappeared, which is an important physiological 
fact, as by the supply of oxygen being cut off, none of the honey is consumed 
in the process of respiration. On the outside of the basement membrane of 
the stomach, is a single layer of branching fibres, (muscular?) The striped 
muscular fibres connecting the abdominal segments together, are collected in 
very thin bands with wide intervals, and are exceedingly elongated.
