712 XOTES FROM THE CAIRD TXSECT HOUSE. 



science in the Caird Insect House, as well as the correction of 

 an error which has caused considerable confusion in connection 

 with the species of Ptinus. We have been handicapped by 

 reduction of staff, our two helpers having joined the colours, 

 otherwise we might have accomplished some other useful 

 research-work with the aid of valuable living material received 

 from various sources. Some day, under happier circumstances, 

 we hope to be able to devote more attention to breeding, etc., 

 thereby adding to the scientific value as well as to the popular 

 interest of the Caird Insect House. 



November 23, 1915. 



Dr. A. Smith Woodward, F.R.S., Vice-President, 

 in the Chair. 



Mr. R. W. Harold Row, B.Sc, F.Z.S., exhibited photographs 

 of an interesting abnormal Frog (Rana temporaria), in which both 

 posterior limbs lacked the hallux, though the calcar, or prehallux, 

 was present on each side. The cha.racteristic structui'e of the 

 digits still existing clearly proved that the missing toe was the 

 hallux, and dissection showed that there was no trace of it 

 internall3\ All the other four digits were perfectly normal. 



A complete description of this abnormality, with illustrations, 

 will be published in the next part of the ' Proceedings.'
