Colony of the Gambia : Quarantine Ordinance, 1916. 



Part of section 34, which deals ■with restriction on embarcation at an 

 infected place in the Colony, states that measures shall be taken to 

 prevent rats in the case of plague, and Stegomyia in the case of yellow 

 fever from gaining access to ships. In the case of yellow fever the 

 ship shall lie at least one thousand yards from the inhabited shore. 

 When access of Stegomyia or rats to the ship cannot be prevented, 

 measures shall be taken immediately before departure of the vessel ta 

 secure destruction of the mosquitos or rats on board. 



Hirst (S.). On the Occurrence of a Tropical Fowl Mite {Liponyssus 

 bursa, Berlese) in Australia, and a new Instance of its attacking 

 Man. — Ann. Mag. Nat. Hist., London, x\iii, no. 104, August 1916, 

 pp. 243-244. 



The Gamasid mite recently described by the author under the name 

 Leiognathus morsitans, sp. n., is now regarded as identical with 

 Liponyssus bursa, Berlese. Specimens of L. bursa were recently 

 obtained from a sitting-hen at Sydney, AustraHa, and were also found 

 attacking man in the same town. The collector suggested that in the 

 latter case, the mites might have come from English starlings which 

 were building in the house- Dermanyssus galUnae does not flourish 

 in tropical and subtropical coimtries, and it is probable that when this 

 species is recorded from such regions, L. bursa is really concerned. The 

 wide distribution of L. bursa may be the result of carriage by the 

 common sparrow.

Investigations carried out in the spring of 1916 in San Diego, 

 California, showed that the yellow fever mosquito, Stegomyia fasciata

 Culex tarsalis, Coq., breeding in fresh and salt-marsh pools ; C. stigma- 

 tosoma, Dyar, found in fresh water without vegetation ; C. comitatus, 

 D. & K., foimd only in artificial receptacles ; C. erytJirothorax, Dyar, 

 confined to permanent ponds ; C. territans. Walk., occurring abundantly 

 in pools in the San Diego River Valley ; C. sp. near derivator, D. & K. ;
