series. Discussing the morphology of the intestine and its derivates in 

 the light of the foregoing, the author defined the large intestine of the 

 Pisces more precisely than had hitherto been done, and showed that the 

 appendix digitiformis of the Elasmobranchs must be regarded as homolo- 

 gous with the appendix vermiformis of mammals, and that a short cacum 

 col'i is present at any rate in the Batoidei. The anatomical relationships 

 of the appendix digitiformis were described in certain Elasmobranchs for 

 the first time, and some notes were added upon the caecum and large 

 intestine among Teleosteans. 



An interesting paper was then read, by Mr. R. A. Grimshaw, on 

 heredity and sex in the Honey Bee. 



Zoological Society of London.

 in the chair. 



The Secretary read a report on the additions that had been made to the

Mr. F. E. Beddard exhiibited and made remarks on some living 

 specimens of an Indian earthworm, Perichceta indica, obtained from a 

 greenhouse in Scotland. 



Mr. A. Thomson exhibited a series of insects reared in the Insect 

 House in the Society's Gardens during the past year, and read a report on 

 the subject. Particular attention was called to specimens of a South African 

 Mantis, Harpax ocellata, and of a Canadian Stick-insect, Diaphemora 

 femorata. 



Mr. Henry Seebohm read a paper on the classification of birds, being 

 an attempt to diagnose the subclasses, orders, suborders, and some of the 

 families of existing birds. The characters upon which the diagnoses were 

 based were almost entirely derived from points in the osteology, myology, 

 and the pterylosis of the groups diagnosed. 



A communication was read from Mr. T. D. A. Cockerell, describing some 

 Galls from Colorado, of which specimens were transmitted for exhibition. 



March 18 —Prof. Flower, C.B., LL.D., F.R.S., President, in the chair. 



The Secretary exhibited (on behalf of the Rev. G. H. R. Fisk) a specimen 

 of a white Bat, obtained at Somerset West, near Cape Town, believed to be 

 an albino variety of Vesperus capensis. 



Capt. Percy Armitage exhibited and made remarks on two heads of the 

 Panolia Deer, Cervus eldi, obtained on the Sittang River, Burmah. One of 

 these was of an abnormal form. 



Mr. Sclater exhibited (on behalf of Mr. Robert B. White) examples of 

 four species of Mammals, obtained in the Upper Magdalena Valley, in the 

 department of Tolima, U.S. of Colombia.
