the filariasis reported from Egypt and Morocco must be transmitted 

 by some other species, perhaps C. pipiens. Other mosquitos in which 

 complete development of F. hancrofti has been observed are Aedes 

 {Stegomyia) variegatus, Dolesch. {scutellaris , Wlk., pseudoscutellaris, 

 Theo.), which has proved a better transmitter in Fiji than C.fatigans, 

 though it is a daytime biter, in connection with which the filarial worms 

 show a reversed periodicity; A. {Finlaya) togoi, Theo., which is an 

 efficient carrier in Japan, where it is a semi-domestic species ; 

 Taeniorhynchus {M ansonioides) africanus, Theo., or the closely allied 

 T. {M.) uniformis, Theo., either of which may be the carrier in 

 tropical Africa ; Anopheles {Myzomyia) suhpicius, Grassi {rossi, Giles), a 

 carrier in India, where it is the commonest semi-domestic Anopheline ; 



A. (M.) costalis, Theo., a carrier in West Africa ; and A. algeriensis, 

 Theo., recorded as a host of F. hancrofti in Tunis, though probably 

 not numerous enough in most Mediterranean countries to be a serious 

 factor in the transmission of the parasite. 



Partial development of F. hancrofti has been observed in twenty-two 

 species of mosquitos, including nine Anophelines and eight species of 

 Aedes. Some of the species in the list given will doubtless prove 

 eventually to be good carriers, but in the case of Aedes argenteus, 

 Poir., it seems definitely established that complete development does 

 not take place. A list of fifteen species is given in which examination 

 has given negative results, though three of these also appear in the list 

 in which partial development has been recorded.

This list of parasites taken from sick or dead animals during 1921 

 includes : Sarcoptes scahiei var. eqiii, Gerl., from the skin of horses ; 

 Haematopinus suis, F., from the skin of pigs ; Trichodectes climax, 

 Nitzsch, from goats' hairs ; Menopon pallidttm, Nitzsch, and Lipeurus 

 variabilis, Nitzsch, from the feathers of a cock ; Gastrophilus pecorum, 

 F. (larvae of all stages) from the stomach of a horse ; and Hypoderma 

 bovis, DeG. (mature larvae) from the skin of cattle.

Owing to evident confusion between Cryptolucilia caesarion, IMeig., 

 and C. cornicina, F. (common blue-green Anthomyiid flies), the main 

 differences between them are pointed out. The generic name Crypto- 

 lucilia, B. & B., has priority over Pseudopyrellia, Girsch., and the genus
