would suggest, interpreting my own and Professor .Lankester’s 
observations, that capillaries of the botryoidal tissue become con- 
verted into capillaries of the ‘ vaso-fibrous’ tissue.” 
The capillaries upon the gastro-ileal portion of the alimentary 
canal are not derived from botryoidal tissue, but are probably 
formed by vacuolation of primitive connective-tissue cells. 
Calomic aud Vascular Spaces——The contractile vacuoles of Pro- 
tozoa, the ducts in nephridial cells, the newly developed vertebrate 
capillary, and all such intracellular spaces, are formed by meta- 
morphosis of the cells themselves, and are thus distinct from 
ceelomic spaces. The formation of intracellular spaces may be 
distinguished as “ endocytic calosis ;” and the formation of inter- 
cellular spaces as “ paracytic cælosis” 
Sensory Cells—Mr. Bourne has traced the connection of the 
nerve with elongated cells, the bodies of which lie beneath the 
epidermal layer. He has overlooked the existence of certain 
peculiar cells, which are probably sensory, as I have shown else- 
where. These sensory cells lie completely beneath the epidermis, 
and are precisely like those found in the eye. 
Mr. Bourne regards the small papillæ, which have a regular 
segmental arrangement in the leech, as tactile organs, and in this 
agrees with Leydig. In speaking of the eyes as “ derivatives” of 
these papillæ, Mr. Bourne might have given me credit for calling 
his attention to this point—C. 0. W.

— On Tuesday last, the 2d inst., a meeting was held in the 
lecture room of the Zodlogical Department, British Museum, at 
which Dr. Coues was invited to attend, in order to explain his 
tg and those of his compatriots on the question of nomencla- 
ure, 
The chair was taken by Professor Flower, F.R.S., and amongst 
the speakers were the following, in the order named: Mr. R. B. 
Sharpe, who opened the proceedings by reading a paper “ On the 
expediency or otherwise, of adopting a trinomial nomenclature in 
zoology ;” ‘Mr. Seebohm, who read a second paper on the sub- 
ject; Dr. Elliott Coues, who explained the system advocated, and 
its application as proposed by him; Dr. Günther, F.R.S., who ap- 
Proved the scheme conditionally; Mr. P. L. Sclater, F.R.S., who 
Pointed out that the method was not a néw one, but thought it 
deserving of adoption by zodlogists, provided the limits of its ap- 
plication were properly defined; Mr. Blanford, F.R.S.; Professor 
BiG]. Bell; Mr. Kirby ; Lord Walsingham; Dr. Sharp; Dr. 
Woodward, F.R S, ; Mr. H. T. Wharton; Mr. Howard Saunders; 
Mr Jz E, Harting, and Dr. Traquair, F -RS. - ‘ 
Various difficulties inthe way of adopting a trinomial nomen- 
clature were pointed out by different speakers ; but, on the whole, 
the Majority appeared inclined to a favorable consideration of the
