Spekia. 



Sjjekia, Bourguignat : Descript. Moll. Egypte, etc., 1879, p. 27; 

 i, p. 35; ii, p. 15, pi. iv, figs. 20-27; pi. v, figs. 1-15; 

 iii, p. 60 ; Martens, p. 205 ; Moore, ii, pp. 256-264, figs. 39-43. 



Spekia zonata (Woodward). 



Lithoglyphus zonatus, "Woodward: Proc. Zool. Soc, 1859, p. 349, 

 pi. xlvii, figs. 3-3c; Smith, i, p. 350; ii, p. 287. 



Lacunopsis {Spekia) zonata, Crosse: p. 122, pi. iv, fig. 4. 



Zacwiopsis zo7i(ita, Pelseiieer: p. 106. 



Spekia zonata, Bourguignat : Descrip. Moll. Egypte, etc., 1879, p. 28 ; 



i, p. 37; ii, pi. iv, figs. 20-24; iii, p. 63; Martens, p. 205, 



pi. vi, fig. 41 ; Moore, ii, pp. 256-264, figs. 39-43, and figs. 



on p. 351 ; i, pi. xxiii, fig. 4. 



The following so-called species have been described which I think 



may be united with S. zonata, namely, S. Cameroni, Duveyrieriana, 



Giraudi, Qrandidieriana, Hamyana, Reymondi (Bourguignat, ii, iii). 



I am inclined to think that there is only one species of this genus, 



varying in the height of the spire and the extent of the basal concavity. 



Tanganyicia. 



Tanganyicia, Crosse : p. 123 ; Martens, p. 204 ; Moore, ii, pp. 246-253, 



figs. 28-32. 

 Tanganikia, Bourguignat: i, p. 41; ii, p. 16, pi. v, figs. 16-21; 

 iii, p. 80. 



Five species described by Bourguignat under this genus may be the 

 young of T. rufofilosa (Smith), and all the twenty -four so-called species 

 of Hauttecoeuria are probably only variations of the same species. The 

 four species of his genus Cambieria also are apparently young stages of 

 this variable shell (see Bourguignat, ii, iii). 



The names are as follows, aiTanged alphabetically : — (1) Tanganikia 

 Fagotiana, Giraudi, Maunoiriana, opalina, ovidea ; (2) Hauttecoeuria 

 Bridouxiana, Brincatiana, Burtoni, Camhieri, Cameroni, Charmetanti, 

 Diweyrieriana, eximia, Giraudi, Hamyana, Jouberti, Lavigeriana, 

 Levesquiana, Locardiana, macrosiomn, llaunoiriana, Milne-edivardsiana, 

 minuta, Moineti, pusilla, Reymondi, Servainiana, singularis, soluta ; 

 (3) Cambieria Jouherti, Maunoiriana, ovoidea, and rufofilosa. (Bour- 

 guignat, ii, iii.) 



This appears to be an appalling lumping of various forms, but 

 I must confess, without having the actual shells described for 

 examination, it seems impossible to do otherwise. 



Tanganyicia rufofilosa (Smith). 



LitJioglyphis rufofilofins. Smith : ii, p. 288, pi. xxxiii, figs. 20, 20«;
