Geruchsgruben des Labiums. 

 Als »Riechgruben« bezeichnete ich in meiner kleinen Schrift 

 «Über Phylloxerinen« p. 74 irrthümlich sechs kleine Grübchen, auf 

 der Innenseite der Saugborstenscheide, fand jedoch bald nach der 

 Veröffentlichung, daß ich mich geirrt hatte und daß es in Wirklich- 

 keit Bö r stehen waren, deren optischer Querschnitt die »Grübchen« 

 vortäuschte. Krassilstschik hat diese Körstchen ebenfalls als 

 «Geruchsgruben« bezeichnet, ist somit in den gleichen Fehler ver- 

 fallen.

1. Zoological Society of London. 



5thJune, 1894. — The Secretary read a report on the additions 

 that had been made to the Society's Menagerie during the month of May. — 

 Mr. S el at er made some remarks on the chief animals that he had observed 

 during a recent visit to the Zoological Gardens of Rotterdam, Amsterdam, 

 Hanover, Berlin, and Hamburg. A communication was read from Dr. E. 

 A. Goeldi, containing critical remarks on the Opossums of the Serra dos 

 Orgâos , Rio de Janeiro, Brazil. — Mr. O. Thomas gave an account, of 

 the Gazelles of Algeria, chiefly based on specimens brought home by Sir 

 Edmund Loder, and distinguished three unquestionable species, Gazella dor- 

 cas, G. Cuvieri , and G. Lodert, the last being a new species of which 

 examples had been obtained by Sir Edmund Loder in the sand-hills three 

 days south of Biskra. A fourth Gazelle, of which a skin and skull had been 

 bought by Sir Edmund I^oder in Algiers many years ago, was referred 

 with some doubt to Gazella corintia ^ the Corinne of Buffon. — Sir Edmund 

 Loder then gave an account of his expedition in search of the »Reem« , 

 as the Gazella Lodert is called by the Arabs, and stated what he had 

 learnt of its habits and distribution. — A second communication from 

 Sir Edmund Loder contained remarks on the period of gestation of 

 the Indian Antelope , as observed in captivity. — A communication was 

 read from Dr. W. B. Benham, containing notes on a particularly abnor- 

 mal vertebral column of the Bull-frog [Rana miigiens) and on certain other 

 variations in the anurous column of this Frog. — Mr. Lindsay Johnson, 

 F.R.C. S., read a communication on the pupils of the Felidae , and stated 

 that, after an examination of the eyes of 180 domestic Cats, as well as the 

 eyes of all the Felidae in the Society's Gardens, he had come to the conclusion 

 that the natural shape of the pupil in Felis is circular. Although under 

 various degrees of light one might get every shape from the circle through 

 all degrees of oval to a perfectly vertical line , yet instillations of atropine 

 or cocaine solutions caused every pupil to become a true circle. The youn- 

 ger the cat the greater the tendency for the pupil to become pointed oval in 

 ordinary light, and, conversely, the older the cat the more frequently did we 

 find a circular pupil. Brilliant light always caused contraction to oval, and 

 direct sunlight to a thin line in the smaller Felidae ; in the larger Felidae
