256 J. G. df; Man : Caridina nilotica. [Voi.. II, 



Museum at Paris ; these specimens have alread}^ been 

 described by me in my paper of 1892 {I.e.). 



3. An egg-bearing female and a younger specimen without 



eggs from the Lake Victoria Nyanza, Bay Kavirondo, 

 received, May 1904, from Prof, E. L. Bouvier, — 

 Caridina wyckii^ Hicks., var. paucipara, de Man ; 

 these specimens were collected, Sept. 1903, by M. 

 Alluaud. ■ 



4. Three egg-bearing females from the river Umgeni, Natal, 



collected Nov. 1894, and received from Prof. Max 

 Weber, — Car. wyckii, Hicks. 



5. Six adult specimens, three of which are ova-bearing, 



from the river Umhlasine, Natal, collected by Prof. 

 Max Weber in 1894 and presented by him, — Car. 

 wyckii^ Hicks, var. paucipara, M. Weber. 



6. One egg-bearing adult female and 60 young specimens 



collected by Dr. N. Annandale, Jan. 28 — 30th, 1906, 

 in brackish water ponds at Port Canning, Lower 

 Bengal. 



7. Fourteen ova-bearing adult females and 48 younger 



specimens collected, Nov. 12th, 1906, in the same 

 locality. 



8. Twenty-four ova-bearing females of somewhat smaller 



size than the preceding and 40 j^oung specimens 

 gathered, Dec. 8th, 1906, in the same locality. 



9. Four specimens, one of which is adult, collected at Dhappa, 



near Calcutta, in slightly brackish water. 



10. Three adult specimens with eggs from the river near 



Palopo, Luwu, Celebes, described by me. I.e., 1892, 

 p. 388, as the typical form of Car. wyckii. 



11. Three adult specimens with eggs, from the river near 



Mbawa, Flores, described b}^ me. I.e., 1892, p. 393, 

 also as the typical form of Car. wyckii. 



12. Three adult females with eggs from Maros, Celebes, 



described by me, I.e., 1892, p. 393, as the variety 

 gracilipes of Car. wyekii (Hickson). 



A punctual and close examination of this large interesting 

 material and accurate measurements of the thoracic legs led to the 

 following results : — 



[a) Caridina longirostris , H. M. Edw., from Oran is not iden- 

 tical with Car. nilotica (Roux) from Egypt, but proved 

 to be (3; distinct variety of it. 



{h) The specimens from Lake Victoria Nyanza ought jjot 



;, • to be referred to the var. paucipara, M> Weber ' ; as 



regards the measurements of their legs, they almost 



fully resemble the var. gracilipes, deM., from Celebes, 



1 Prof. Bouvier in his valuable paper on the Atyidce (I.e., 1905), erroneously 

 supposes this variety to have been described by me.
