These names are to be by preference those which have come into general 

 use in the fifty years following their publication, especially those generic 

 names upon which long used family names are based and those which 

 have been used in monographs and important works up to the year 1890. 

 With each generic name thus conserved is to be cited a type species, to 

 be chosen with a view to retaining the name in its most widely known 

 sense, even if thereby an exception must be made to the other provisions 

 of this code. 



Several additional propositions will be made public in the near 

 future.

Abstract of Proceedings. August 28th, 1912. — Dr. J. B. CI eland 

 showed Cysticercus tenuicollis and Echinococcus veterinorum from sheep, 

 illustrative of the way in which the perpetuation of the specis is provided 

 for during the eating of such cysts by dogs. In G. tenuicoliis, only one head 

 of a future tapeworm [T. marginata) is found in each cyst. It is of consider- 

 able size, and would he easily crushed by the teeth of a dog, if it were not 

 for the fact that the cyst hangs dependent from the liver or abdominal organs 

 of the host. The dog, in eating these, after hasty chewing, swallows part of 

 the organ which, as it descends, draws after in the dependent cyst which 

 had been hanging outside the dog's mouth. In the Echinococcus, numerous 

 scolices, representing immature heads, cover the inside of the walls of the 

 (non-sterile) cysts; however many may be crushed by the dog's teeth, nume- 

 rous others escape to perpetuate the species. — Mr. G. A. Waterhouse 

 exhibited specimens of Euplœa Corinna Macleay, from Sydney, Brisbane, 

 Cairns, Cape York, and Port Darwin. These demonstrated that this species 

 is not subject to geographical variation in Australia. At Cape York, occa- 

 sional aberrations occur, in which the white spots are reduced in size; more 

 rarely some of the white spots are absent. Miskin described two such aber- 

 rations (q^Q) under the name Euplœa euclus] but the present exhibit not 

 only showed examples even more divergent from typical Corinna than Mis- 

 kin's specimens, but also intergrades between E. Corinna and E. euclus. In 

 a note upon the exhibit Mr. Waterhouse said: "Dr. K. Jordan has kindly 

 examined, for me, Felde r's types of this genus in the Tring Museum. He 

 has written to me that Euplœa angasi Felder, is identical with E. Corinna] 

 the type of E. angasi shows the single brand in the q?. The second of 

 Felde r's species recorded from Australia is E. lewini, which is without a 

 brand in the cf. Dr. Jordan considers that the locality given is incorrect, 

 and with this view I quite concur; no Euplœa known from Australia agrees 

 with the description of E. lewini" E. boisduvali Lucas, is probably another 

 synonym. — Mr. Froggatt exhibited living specimens of a large Mealy 

 Bug (Monophlebus crawfordi Mask.) sent to him from South Australia, to 

 show the large quantity of white, mealy wool produced by this species. He 

 showed also examples of the trap-door nests of three unidentified spiders,
