1 8 Henry B. Ward 



55. Annett, Button, and Elliott (1901) record that at Bonney 

 they were fortunate enough to obtain a single female of this 

 species for their collection. Since nothing is said regarding host 

 and location, it is fair to assume its removal from the usual place, 

 the eye of man. 



56. The same authors received a female parasite taken from 

 the eye of a Kroo boy by Dr. A. H. Hanley, medical officer at 

 Opobo. In the blood of the host were embryos most similar to 

 Manson's F. diurna. 



57. Dr. A. H. Hanley also sent a male F. loa from the eye of 

 a Kroo boy whose blood had no embryos at all. This case is 

 recorded by Annett. Dutton, and Elliott, 190 1. 



58. In 1902 Dr. Milroy removed from a man who had been a 

 missionary in Batanga a male F. loa. It was first observed in 

 1899. The case was first published by Ward (1902), but the 

 full account by Dr. Alilroy is found in this paper. 



59. Dr. Rennes removed two specimens of F. loa from a Eu- 

 ropean in Sierra Leone, where no previous case had been noted. 

 The patient had been living in the Congo and had been in Sher- 

 boro only one year. One worm was removed from the eyelid 

 and the other from the loose skin of the penis. The blood of 

 the patient was swarming with embryos. The case is recorded 

 by Prout, 1902. 



60^61. Dr. Thompstone removed two males and two females 

 from natives of Opobo, Nigeria, and sent them to Dr. Manson of 

 London. They were described by Ozzard, 1903. No data are 

 given regarding the hosts, but they were probably natives. 



62-67. Af the mission station of Yakusu near Stanley Falls, 

 upper Congo river, j\Ir. S. S. found F. loa very common among 

 natives. He saw at least six cases. The record was published 

 by Manson, 1903. 



68. Dr. Frederick Fenton of Toronto, Canada, removed two. 

 worms from the eyelid of a patient in September and December, 

 1898, and failed in 1899 in the effort to secure a third. The case 

 was presented to the Toronto Pathological Society, but not pub- 

 lished. It was noted briefly by Primrose (1903) and is pid)iished 

 m full in the present paper (pp. 6-8).
