Mr. Ayres said that lie had observed similar malformations in 

 fish, as in the case of the Bass exhibited at the meeting of Feb- 

 ruary 21st, 1849. He had also been informed by Prof. Agassiz 

 that such deformities are occasionally found in the European 

 Trout. Mr. Ayres remarked, that the specimens before the So- 

 ciety, with those he had before seen, made up the number of 

 five, that had come under his observation with this malformation, 

 in three genera. 



Dr. Wyman made a report on the cranium of the 

 Engeena (Troglodytes gorilla) recently presented to the 

 Society by Dr. George A. Perkins of Salem ; also on that 

 belonging to the Essex County Natural History Society. 



The first skull was that of an adult male, as was indicated by 

 the fact, that the teeth were all protruded, though they were not 

 worn. As in the crania formerly described, the sutures were 

 for the most part obliterated. He thought there were indications 

 that the portion of bone, which was found between the inner orbi- 

 tar angles of the frontals, and which was described as the ascend- 

 ing portion of the nasals by Mr. Owen, was an independent piece, 

 and had a centre of ossification of its own. 



He had measured the capacity of this cranium, and of three 

 other crania of the Engeena and found it as follows : — 



I. Male, 34.5 



II. Male, 28.3 



III. Male, 28.0 



IV. Female, 25.0 



Dr. Wyman was disposed, after an attentive examination of the 

 anatomical evidence, to regard the Engeena as occuping a lower 

 position in the Zoological series than the Chimpanzee ( T. niger.) 

 Its brain was proportionally smaller, the molar teeth were more 

 pointed, the canines larger, the wisdom tooth was of the same 

 dimensions as the other molars. Several other characters ex- 

 isted which indicate its lower position.
