this author having identified it among some Persian fossils 

 obtained from the Siokuh mountains. Lamarck's original speci- 

 men is localised as from Yence, near G-rasse in Erance, which 

 Puchs considers as belonging to the " Horner Schichten " 

 division of the Miocene ; it has been well figured by Fontannes, 

 who tabulates it as of Lower Helvetian age. This species forms 

 the type of Saeco's sub-genus Oopecten, and its range in Italy, 

 according to the same author, is from the top of the Aquitanian 

 into the Helvetian. 



Locality. Seir Hill, 6-8 miles west of Urmi. 



Formation. Miocene (Helvetian or Burdigalian ?). 



Pecten (Elabei/Lipecten) sp. indet. 



This determination refers to a fragmentary pectinoid shell 

 exhibiting a very slightly convex lower valve, with about 16 

 rounded radial costse separated by very wide interspaces, some 

 obscure concentric striations on the ribs and grooves being dis- 

 cernible in places. 



It is probably an example of P. Besseri, Andrejowski, from the 

 Polish Miocene (Bull. Soc. Nat. Moscou, 1830, vol. ii. pi. 6. fig. 1, 

 p. 103), but the intercostal grooves are mostly filled with matrix, 

 and the specimen is otherwise so poorly preserved that a more 

 definite identification is not possible. 



There is no doubt as to its belonging to Sdcco's sub-genus 

 Flalellipecten, of which the type h P. fiahelliformis., Brocchi, sp. 



Locality. Prom the beach of the island of Koyun Daghi.

The collection contains five fragments of a Pectinoid shell which 

 appear to be the equivalent of that form regarded by Dr. Abich 

 as allied to P. Malvince of Dubois de Montpereux (Conch. Poss. 

 "Wolhyni-Podolien, 1831, pi. 8. figs. 2, 3, p. 71). The most com- 

 plete example has from 18-20 narrow, rounded costse, extremely 

 fine at the umbone, but afterwards widening, and separated by 

 deep grooves ; the lateral ribs having a tendency to curve. The 

 entire surface is covered by fine, equidistant, transverse, imbri- 

 cating or squamose striations. The shell is probably a ovm 

 form, as there is no indication of the ribs dichotomizing.
