astroea, tlie septa are seldom preserved ; but tliey are shown in 

 a few corallites of the Koynn Daghi example. The species 

 occurs in Egypt *, but has not, so far as I am aware, been pre- 

 viously recorded from Asia Minor or Persia. Abich f quotes a 

 ^olenastrcea astroites from Lake Urmi, and that record may have 

 been based on S. turonensis. Abich did not give figures, and 

 accepted the species for the Sarcinula astroites (Goldf.);];, which, 

 according to Milne-Edwards & Haime §, is a synonym of Orhi- 

 cella Mlisi (Defr.). That determinatioa is quite consistent with 

 Goldfuss's instructive figure. Abich quoted as a second refer- 

 ence the Solenastrcea columnaris (E.ss.)||, wbich appears quite 

 distinct both from " Sarcinula astroites " and from Solenastrcea 

 turonensis.

This species has been recorded from Armenia by Abich, who 

 has figured a specimen collected between Main and Khoi, which 

 shows the deep steep-walled ealicular fossa of this species. 

 Mr. Griinther's collection includes two specimens from Lake 

 Urmi, exact locality not stated.

 This species was recorded by Abich from Koyun Daghi, but 

 his figures alone are not convincing of the specific identification. 

 Mr. Giinther has collected two other specimens from the same 

 locality, which enable the characters to be more fully determined. 

 The Armenian specimens differ from Milne-Edwards and Haime's 

 diagnosis in the more solid nature of the exotheca and in the 

 apparent absence of the numerous granulations on the costas, 

 wliich are said to be visible on worn specimens. The specimens 

 from Koyun Daghi are extremely worn, and it may be that the
