characteristic. The tail is flat, curved a little upward, and ridged 

 along the middle in imitation of the attenuated caudal column. 

 The general consistency of this work is demonstrated by the fact 

 that this particular form of tail accompanies this form of head in all 

 cases, and is not associated with any other. The face of the bat is 

 always turned toward the vessel ; on other varieties, it is nearly al- 

 wavs turned out.

 In one case, Fig. ^6, we have, what appears to be, a human head 

 attached to the side of the bowl. This head is furnished with a tri- 

 angular crest, notched on the edges, and enlarged at the top. The 

 case is a perplexing one, especially as a tail like that attached to 

 the bird bowls occurs on the side opposite the head. 



rOT-SHAPED VESSELS. 



There is no hard line of demarkation between the class ofvessels 

 now to be considered, and those already described. The distinc- 

 tion is made chiefly for convenience of treatment. 



Material, etc. — As a rule, pot-shaped vessels are of coarser ma- 

 terials, and of ruder finish than other forms, indicating, perhaps, 

 their exclusive relegation to the culinary arts, where nice finish was 

 not essential. In many cases they show use over fire. 



In size, they have a wide range. The larger are often as much 

 as fifteen inches in diameter, and twenty in height. There are a 

 score or more of very large size in the museum. 



Form. — The form characteristics are a full globular body — some- 

 times elongated, sometimes compressed vertically — a low neck, and a
