Amazonas. — Ann. Trop. Med. & Parasit., Liverpool, xvi, no. 3, 

 18th October 1922, pp. 297-300. 

 Of 50 stray dogs, examined post-mortem in Manaos, 11 were found 

 to be harbouring the flea, Ctenocephalus canis, and two the tick, Rhipi- 

 cephalus sanguineus. Neither parasite was found on cats.

pogonine Midges on the Windows of the Accra Laboratory during 



a completed Year. — Ann. Trop. Med. & Parasit., Liverpool, xvi, 



no. 3, 18th October 1922, pp. 301-304. 



The number of Ceratopogonine midges thus collected during the 



year was between 3,000 and 4,000. Besides those already recorded 



from windows [R.A.E., B, ix, 26], they included Ctilicoides similis, 



C, I. & M., Thysanognathiis marmoratus, C, I. & M., Centrorhynchus 



{Lasiohelea) inconspicuosus, I. & M., ms.., Forcipomyia castanea, Wlk., 



F. incomptifeminihus, Aust., F. ingrami. Cart., which, with Culicoides 



schidtzei, End., is the most abundant throughout the year, F. inornati- 



pennis, Aust., F. hiannidata, I. & M., ms., and F. squamipennis, I. & M., 



ms. Species of which only one or two individuals were taken include 



T. maculipennis, C, I. & M., T. macvdithorax, C, I. & M., T. pseudo- 



inaculipennis, C, I. & M., Dasyhelea flavipicta, I. & M., Atrichopogon 



acosmetum, I. & M., A. africanum, I. & M., A. chrysospherotum, I. & M., 



A. elektrophaeum, I. & M., A. kelainosoma, I. & M., .4. perfuscum, 



I. & M., A. xanthoaspidum, C, I. & M., and F. hirsuta, I. & M., ms. 



The commonest mosquitos captured during these collections were 

 Aedes argenteus, Poir. {Stegomyia fasciata, F.), Culex fatigans, Wied., 



C. decens, Theo., and Aedes (Ochlerotatus) irritans, Theo.

 Region of the Amazon. — Ann. Trop. Med. & Parasit., Liverpool, 

 xvi, no. 3, 18th October 1922, pp. 315-338, 1 pi., 10 figs. 



The majority of the mosquitos dealt with were caught in the forests, 

 about 15 miles from Mandos, on the Rio Negro. No Anophelines were 

 discovered in the forest, the only one recorded. Anopheles {Cellia) 

 alhimanus, being taken on the outskirts of Manaos. 



New species described are : Sabethes amazonicus ; Wyeomyia 

 negrensis, from larvae in the stem of Bananeira braba (wild banana) ; 

 Culex originator, from natural holes in the bark of Carapana uba ; 

 Aedes [Finlaya) oswaldi, Lutz, var. braziliensis, n., from a hollow in 

 a tree-stump ; Megarhinus horei, in stems of B. braba, this being a 

 carnivorous species the larva of which readily destroyed larvae or 

 pupae of Ctdex fatigans [quinquefasciatits); and Uranotaenia calosomata, 



D. & K., var. albitarsis, n., breeding in an old iron receptacle.

 Sickness from the Sudan. — Ann. Trop. Med. & Parasit., Liverpool, 

 xvi, no. 3, 18th October 1922, pp. 339-340. 



Three cases of human trypanosomiasis are recorded from Tembura. 

 The morphological characters of the trypanosome concerned and its 

 pathogenicity for various animals justify the conclusion that it is 

 Trypanosoma rhodesiense. The insect vector concerned remains to 

 be discovered, but it is significant that Glossina. palpalis {fuscipes) 

 and G. morsitans are ubiquitous in the district.
