shorter, and may be said almost to belong to the Brachycephali. No. 693, the 

 fnc simile of the Pocasset skull just referred to, is a peculiar head. The coro- 

 nal region is irregularly oblong ; the head widens out backwards from the os 

 frontis, attaining its greatest width between the parietal centres of ossification. 

 Moreover, the low receding forehead slants upwards to the same interparietal 

 diameter. The broad posterior region slopes downwards to the foramen mag- 

 num, as if pressed under the overhanging parietalia. Nos. 050, (female,) 951, 

 (male, ) 954, (female, ) 957 (male) and 1040, (female, ) are oblong heads, having 

 for the most part the superior occipital flattening seen in Swedish crania, and 

 also the protuberant occipital process, which is of the usual size and appear- 

 ance in Nos. 950 and 954, and forms a very large triangular knob in No. 951, 

 projecting in a straight line beyond the inferior and posterior edges of the 

 parietalia, as in the Swedish skull, No. 1249. In No. 957 the protuberance 

 disappears, or is very much softened down, in consequence of the cone-like 

 manner in which the whole posterior region converges to a blunt point. The 

 basal surface of the occiput is non-symmetrically flattened, the right half be- 

 ing pressed up towards the parietals more than the left. This flattening is 

 probably posthumous. In No. 955 we have another instance of this appa- 

 rently posthumous deformity. The highest point of the vertex in No. 957 is 

 at the anterior fontanelle. In No. 1040 the protuberance of the occiput over- 

 hangs the basal portion like a ridge. In this skull is also exhibited the basi 

 occipital flatness which, as we have just seen, characterizes the Minetari 

 skulls. No. 952 is asymmetrical, the right half being a little shorter than 

 the left. No. 953 belongs to the arched type. A slight flatness is observable 

 in the posterior, inferior part of the parietalia, but the occipital bone curves 

 regularly round to the foramen magnum without any flatness whatever. The 

 same remarks apply to No. 956. Nos. 953 and 957 are remarkably prognathic. 

 In No. 953 the prominence of the maxilla? gives to this skull a negrodike ap- 

 pearance. 



A Naumkeag skull (No. 567) from Salem, Massachusetts, is a long, narrow 

 oval head with a projecting occiput, and a high coronal region which is dis- 

 tinctly carinated. 



Five Natick skulls from Nantucket, upon the whole, appertain rather to a 

 form intermediate between the Dolicho- aud Brachycephali, than to either 

 one of these classes. The elevated vertex and but moderately prominent oc- 

 ciput give to No. 103 the arched form. No. 104 is a longer head, with a 

 flatter crown and a more protuberant occiput. No. 107 is an oblong, dolicho- 

 cephalic head. In No. 110 the upper part of the hind head is flat, and the 

 protuberance of the occiput lozenge- shaped. 



The Natick and Narragansett skulls may be said to represent the woolly- 

 haired African form. 



The Lenape or Delaware Indian skulls in the Academy's collection, also 

 fall, for the most part, into the dolichocephalic class. With the exception of 

 Nos. 205, 206 and 1263, they are long, though not strikingly narrow heads. 

 The general outline of the coronal region resembles that of the Arickarees, 

 Assinaboins, Cherokees and Iroquois, occupying a place in fact between the 

 latter two. The occipital boss, though protuberant, is less so than in the 

 Arickaree, Assinaboin and Cherokee heads. The occipital region is superiorly 

 flattened. The upper jaws are more salient than in the heads already de- 

 scribed, amounting in the female skull, No. 40, as shown in Crania Americana, 

 plate 32, to negro-like prognathism. No. 1263 may be regarded as a Brachy- 

 cephalus. In consequence of the posterior, interparietal diameter being 

 greater than the frontal, the contour of the coronal region differs from that of 

 the others of this group, and resembles that shown in some of the German 

 skulls, especially No. 706. The posterior region is broad and perpendicularly 

 flattened. The coronal outline of No. 1265 resembles in some respects that of 

 No. 1263. Nos. 205 and 206 dug up from a street in Philadelphia, and sent 

 to the Academy as Delaware Indians, are very similar in form to Nos. 1263 



1866.]
