200 Kart WILHELM GENTHE, Some Notes on Alcippe lampas (Hanc.). 
The two cirri were pressed a little downward and to the sides. 
The stiff bristles, dilatatores oesophagi, mouth and mouthparts 
are shown. The mandibles are seen edgewise. 
Fig. 13. Head in side view. 
The oral cirrus, palp, mandible and first and second maxilla 
of the right side and the oesophagus are shown. The two 
“apodemes” extend towards the spur-like chitinous process. The 
mandible is seen as it appears in side view, the large tooth lies 
downward in the frontal plane and does not show. All the parts 
are in their natural position. 
Fig. 14. Head in oblique view. 
Both palps and all the mouthparts are shown. The four 
“apodemes” extend towards the chitinous spur. The preparation 
from which this sketch was made was evidently a trifle distorted 
thus bringing all the parts at once into good view. 
Fig. 15. Frontal section of the body. 
The body of an animal was taken and with a razor was cut 
into four frontal sections. The section here given shows in 
outline the head and oral cirri. We look down on the mouth- 
parts from behind. The upper division of the stomach is shown 
with its folds and pits and we look down into it. The lower 
portion of the stomach was cut so as to leave only a ring in 
our section. 
Fig. 16. Sagittal section of the body. 
The body of an animal was halved with a razor, stained with 
paracarmine and mounted in balsam. The drawing had to be 
combined from several preparations and to be made somewhat 
diagrammatic. The whole digestive tract is shown. The muscles 
except those around the digestive tract and the second and third 
retractor are mostly omitted.
