passing across tlie horizontal oval, {e.) A puppy, in wliicli 

 also the proboscis is above the eye, as in the case of the pigs, 

 and in otlier respects very similar to the above. (/) A 

 kitten, with one eye, in which there are two well-formed 

 pupils; here also the proboscis comes from the forehead. 

 {g.) A very young foetus (calf?), in which there is but a 

 single eye, with one pupil and one cornea. At the junction 

 of the ocular and palpebral conjunctivae there is a deep fold, 

 and the eye is smaller than in most of the other specimens. 

 There is no proboscis, and the upper jaw below the eye is 

 much depressed. The tongue is very much protruded. 



{h) Cyclopean lamb, in which there is a single eye, with 

 a partial division of the pupil ; the upper jaw is characterised 

 by the same depression that is found in the calf (?). In it 

 there are no teeth, but simply a series of rough papillae. 

 The investing skin and mucous membrane extends for some 

 considerable distance beyond the bone. In the lower jaw, 

 which also protrudes somewhat, there are six teeth already 

 erupted. 



(i) Skull of Cyclops puppy. In this the occipital, parietal, 

 temporal, and malar bones are all normal. The frontal bones 

 are fused together, and there are no traces of nasal bones in 

 this macerated skull. The two superior maxillary bones are 

 firmly fused, and there are no traces of pre-maxillary bones. 

 There are three teeth in the upper jaw — two lateral teeth, 

 corresponding in position and appearance to canines, and a 

 central tooth, the fang of which is not imbedded in the 

 superior maxillary bone, but lies in front of the alveolar 

 arch. It is, however, supported by two small spicules of 

 bone, which pass forwards, one on each side. They do not 

 reach to the front of the fang, where the tooth is covered by 

 mucous membrane only. The palate bones are fused in the 

 median line, but not ossified to the superior maxillae. The 

 vertical plates of the palate bones are fused and twisted so 

 as to present anterior and posterior surfaces. These, with 

 the internal pterygoid processes, form the anterior wall of the 

 naso-pharynx, which extends forwards for some little distance 

 above the horizontal plates of the palate bones. There are 

 no indications of posterior nares at the bottom of this de-
