iella. This union I have proven to be inadmissible on the ground 

 of the totally different dentition of the radula. 



Professor Tate's note, therefore, does not in the least affect the 

 conclusions reached in ray paper, viz., that Tatea is a valid genus 

 of Amnicolidce ; that it is not at all closely related to the Bissoini- 

 nce; and that it is not equivalent to the genus Eatoniella. 



It only remains to add that the paper of my esteemed colleague 

 may be consulted with advantage for the full specific synonymy, 

 and for details of the external anatomy of Tatea not given in my 

 own communication.

General Isaac J. Wistar in the Chair. 



Thirty- six persons present. 



A paper entitled " Odonata (Dragonflies) from the Indian Ocean 

 and from Kashmir collected by Dr. W. L. Abbott," by Plrilip P. 

 Calvert, was presented for publication. 



The following was offered from the Anthropological Section : — 

 The Anthropological Section of the Academy of Natural Sciences 

 views with the deepest regret the untimely death of its late able 

 and esteemed Director, Dr. Harrison Allen, to whose earnest 

 efforts the organization and subsequent success of the Section were 

 mainly due and who served it as Director from its first meeting 

 until his decease. Dr. Allen's broad interest in the science of 

 anthropology in general and his valuable series of studies in the 

 characteristics of huraan crania in particular, were indicated by 

 numerous communications to the Section, of which one, on a new 

 method of estimating the comparative measurements of skulls, 

 given in October, 1897, was probably his last communication before 

 any scientific body. The high value and wide diversity of his 

 scientific work, the originality and suggestiveness of many of his 

 views and the deep earnestness of his devotion to scientific research 

 render his death a serious loss to the world of science as a whole, 

 and in particular to the institutions with which he was intimately 

 connected. By the Anthropological Section it is felt to be a loss 

 which cannot easily be repaired. 



The communication above alluded to has been reported as 

 follows : —
