(15) That no such bodies as cones exist in Hinulia. 



(16) That the epiphysis as in Calotes, Seps, etc., is sep- 

 arated from the eye, and that no such structure as the pineal 

 stalk is present in either of the forms examined. 



(17) That the eye may be supposed to draw its blood from 

 the large vessel so constantly present directly beneath it. 



Strahl and Martin 1 (6*7-' 88). In Lacerta vivipara the stric- 

 ture of the epiphysis to form the eye takes place in a different 

 way from that described in Anguis. In Lacerta there is a sim- 

 ple evagination from the roof of the diencephalon, which is sep- 

 arated into two equal contiguous sections by a depression from 

 above. In Anguis, on the other hand, nearly the whole pri- 

 mary evagination is changed into the eye and only the smallest 

 remnant is left for the epiphysis. This remnant soon, however, 

 changes its distal part by growth. 



Francotte 1 (21-88) described the pineal as a development 

 from an optic vesicle which arises from a diverticle of the distal 

 part of the cerebral part of the epiphysis. In describing 

 the distal portion of the parietal nerve Francotte overlooked 

 the proximal portion, a fact which is astonishing since he had 

 an abundance of material. He supposed that it is attached to 

 the anterior surface of the proximal part of the epiphysis. 



Johannes v. Moller (60— '90) states that only two papers 

 have appeared on the pineal gland of the chimpanzee, the 

 one by 



Marshall (52—61), in which he merely states that the 

 chimpanzee brain has a large delicate epiphysis without brain 

 sand. The other is by Moller himself (60) where he describes 

 the pineal as follows : The pineal, deeply imbedded in pial 

 plexus which is removed from it with difficulty, lies in the fur- 

 row between the anterior pair of the corpora quadrigemina. Its 

 form is such that we can distinguish first, an unpaired stalk 

 which, with the pedunculi conarii branching from its anterior 

 end, makes up by far the greater part of the pineal mass, and 

 second, the samll nodule situated at the caudal extremity of the 



'Fide Klinkowstrom.
