In der ersten waren 250 Stück Brut, davon 30 mit Mopsköpfen, 
der Rest normal. 
In der zweiten bloß 180 Stück Brut, dagegen 50 mit mehr 
oder minder deutlichem Mopskopf. 
Eine dritte ebenso wie die im Voraufstehenden skizzierten be- 
schaffene, nur etwas weniger tiefe Grube hatte ich mit vier laichfähi- 
gen normalen Moderlieschen, zwei g' und zwei ©, besetzt, deren 
»Großeltern« Mopsköpfe gehabt, während die Eltern wohl- 
gestaltet gewesen waren. Sie erzielten 210 Stück Nachkommen- 
schaft, und zwar 20 abnorme, den»Ahnen«ähnelnde, und 190 
normale. 
Natürlich denke ich diese interessanten Versuche im Laufe des 
bevorstehenden Frühlings fortzusetzen und die gewonnenen Resultate 
seiner Zeit an dieser Stelle wieder zu publicieren.

28th February, 1893. — Mr. A. D. Michael, F.Z.S., exhibited some 
specimens of the Zrodes, known locally in the West Indies as the »St. Kitts« 
or »Gold Tick«, received from Mr. C. A. Barber, of the Agricultural De- 
partment, Antigua. — A communication was read from M. A. Milne- 
Edwards, F.M.Z.S., respecting Lemur nigerrimus, Sclater, a species of 
Lemur originally described from an example living in the Society’s Gardens. 
It was pointed out that Prosimia rufipes of Gray had been based on a female 
of this species. — Mr. Howard Saunders, F.Z.S., exhibited and made re- 
marks on a specimen of the American Stint (Zringa minutilla), shot at Nort- 
ham Burrows, North Devon, by Mr. Broughton Hawley in August 1892. — 
Mr. Sclater (on behalf of Mr. R. M. Barrington) exhibited a specimen of 
the Antarctic Sheathbill (Chionzs alba), killed at the Carlingford Lighthouse, 
co. Down, Ireland, in December last. — Dr. C. J. Forsyth-Major, 
C.M.Z.S., read a memoir on some of the Miocene Squirrels, and added re- 
marks on the dentition and classification of the Sciuridae in general. The 
author proposed a new division of this family into three subfamilies — Sci- 
urinae, Pteromyinae, and Nannosciurinae. The genera Spermophilus and 
Arctomys and the allied forms were united to the Sciurinae. The last part of 
the paper dealt with the primitive type of the Sciurine molar. — Mr. Henry 
O. Forbes, F.Z.S., read a paper entitled »Observations on the Develop- 
ment of the Rostrum in the Cetacean Genus Mesoplodon, with remarks on 
some of the Species«. Mr. Forbes showed that in this genus the vomerine 
canal in the young animal is filled with cartilage, and in the adult with a 
dense petrosal mesorostral bone. From the examination of 13 specimens of 
Mesoplodon Grayi and 4 of M. Layardi, of which he had made a large num- 
ber of sections in various stages of growth, the author concluded that the 
mesorostral bone was not, as had been generally believed, an ossification of
