in Thug No. 130, with the retreating forehead, was 2 '6, whilst in No. 131, in which the 

 forehead was more highly arched, the proportion of base line was 2*7. 



Addendum, 29th June. — Since this memoir was read, Professor Cunningham has 

 called my attention to the skeleton of a Tamil Sudra from Mysore, which was presented 

 to him for the Museum early in June, by Mr R. B. Thomson, M.B. It had been brought 

 from Madras by an Indian student from the College of Medicine in that city. 



The skeleton was a male, in which the ossification was completed, though the wisdom 

 teeth had not erupted. The skull was elongated, ovoid, dolichocephalic, Ceph. Ix. 71. 

 The glabella and supraorbitals were well marked, the nasion was depressed, the sutures 

 were unossified, the pterion was normal, and the muscular ridges and processes were 

 distinct. A special feature was the large interparietal bone which took the place of the 

 occipital squama above the inion and superior curved lines. The occipital condyls 

 were deeply cleft at the inner border ; the posterior condylar foramina were absent ; a 

 pair of stunted processes projected downwards from the basi- occipital immediately in 

 front of the basion. The basi-bregmatic diameter exceeded the greatest breadth, and 

 the vertical index was 73 '7. The upper jaw was orthognathic, 95. The complete facial 

 index, 94'5, and the maxillo-facial index, 51*1, were leptoprosopic. The bridge of the nose 

 was moderate, the nasio-malar index being 109 ; the nasal index, 49'9, was mesorhine. 

 The orbital index was microseme, and the palato-maxillary index was hyperbrachyuranic. 



The pelvis had distinct male characters. The iliac bones were expanded and the 

 fossae were translucent ; the tubercle on the crest and the muscular ridges were moderate ; 

 the praeauricular sulcus was a shallow groove. The cotyloid notch was wide, the 

 pectineal crest and pubic spine were moderate. The body and neural arch of the first 

 sacral vertebra were not fused with the second. The neural arches of the 2nd, 3rd, and 

 4th sacrals formed a continuous plate. The first coccygeal vertebra was fused with the 

 body of the 5th sacral, and in each of these bones the cornua were strong though not 

 continuous with each other. The following measurements were taken : —
