The researches of the autliors and others liavo sliown that in 

 French Equatorial Africa the " Cayor worm '' and allied species 

 are rare. One case, however, was discovered at Nola in 190T, 

 when a European was parasitised by two larvae in his left arm ; 

 now others have been reported from Sembe in N'Goko, where two 

 Europeans and a native woman living in the vicinity were simul- 

 taneously attacked, and 13 larvae in all were extracted. In 

 no case were the flies bred out, but it is believed that the species 

 was C())-(hih)l)in rodliaini, Gedoelst, rather than (' . anfhrojxipliarja, 

 Grunb. The former has hitherto only been observed in the 

 Beljiian C'ono-n, espocinlly about Loopoldville.

The author has given the name of Baccellia anopheliae, g. n., 

 sp. n., to a parasite not previously discovered and apparently 

 very rare, the complete evolution of which seems to take place 

 in the digestive tube of Anoplielcs waculipemnis. The figures 

 show the division of the free parasite into karyosomes, tlic various 

 forms of niultiplicatiim and the encystment.

The author begins by recapitulating the previous epidemics 

 on board the despatch transport the " Manche," on which 114 

 out of 12T Europeans were attacked by dengue fever in 190G, 

 94 out of 108 in 1907, and 2 in 1908, when the disease was 

 circumscribed from the outset. In 1911 there were 91 cases 

 among 120 Europeans. On each of these occasions the Annamite 

 lascnrs, of whom there were 34 in 1911, remained completely 

 immune, as did also all the Europeans who had been attacked 

 l)efore. The origin of the outbreak cannot be determined. The 

 " Manche" left Saigon, the chief centre of dengue in Indo-China, 

 on 171 h August 1911, stopped for 24 hours in the Bay of Gam- 

 Pinnh, went on to Nhatrang, another centre, remained there till 

 18th September, and arrived at Tongking on the 24th, having put 

 into Turan Bay for 24 hours on the way thither. The first case 

 broke out at Nhatrnug on (Hh Se])temb!>v, the last at TIai])hong
