ON BIBDS FROM EQUATORIAL AFRICA. 419 



Were there symmetrical growth, and did the costse radiate 

 from a common centre, the form would come within the genus 

 Micrabacia (Edwards and Haime, Hist. Nat. des Corall. vol. iii. 

 p. 30, 1860). The genus is therefore a very interesting addition 

 to the family Funginae, and must be placed between the genera 

 Fungia and Micrahacia. 



It is mimetic of the genus Diaseris of the Lophoserinse.

[Eead 1st May, 1884.] 

 I OWE the opportunity of examining the interesting collection 

 described in the present paper to the kindness of Mr. Bohudorff, 

 who has just returned to Europe, after a hazardous passage 

 down the Nile and across the desert of Korusko to Cairo. Mr. 

 Bohudorff has been collecting in Africa for the last ten years, 

 but has had the bad fortune to lose most of the results of his 

 labours, his largest collection, the outcome of two years' toil, 

 having been utterly destroyed when he fell into the hands of 

 Zebehr's son, Suleiman, and the rebel troops at the time when 

 General Gordon went out to Equatorial Africa as Governor- 

 General of the Soudan for the first time. Stripped of everything 

 he possessed and barely escaping with his life, which he owed 

 to the intervention of an Egyptian officer, Achmed Effendi 

 void el Cheter, who concealed him in the guise of a female
