life of the species of Productus. A small species is described which is 

 found attached to the stems of Crinoids or to other foreign bodies. The 

 mode of attachment is by the spines, which are wound round the foreign 

 body, the ventral valve being also sometimes attached directly by its 

 substance. In its adult state this parasitic form approaches more 

 nearly to P. Wiicjlitii than to any other ; and the name P. complectens 

 is suggested provisionally. Describes and figures, without naming, a 

 species oi Sjyirifenna^ allied to P. inscalpta, Phill., though differing in 

 some points. H. A. N. 



Etheridge, R., Jun. Notes on Carboniferous Mollusca. Geol. Mar/. 

 dec. ii. vol. iii. pp. 150-156, pi. vi. 



Describes as a new species Vincidaria Benniei from Peeblesshire. In 

 addition Aviculojjecten ? suhlohatus^ Phill., and A. papyraceus^ Sow., 

 are fuUy described and figured ; colour-bands are noted as occurring on 

 the shell of the former of these and of Avicidopecten planoradlatus^ 

 M'Coy : and the varietal name of undatus is given to a well-marked 

 form of Belleroplion decussatus^ Fleming. All the specimens described 

 are from the L. Carboniferous rocks of Scotland. H. A. N. 



South Australian Post-Tertiary Foraminifera and Ostracoda. 



Geol. Mag. dec. ii. vol. iii. p. 334. 



Gives a list of 24 species of Foraminifera and 4 species of Ostracoda 



occurring in the Post-Tertiary [Miocene, R. Tate, 1877] beds of the 



Murray River Flats, S. Australia. R. E., Jun. 



Carboniferous and Post-Tertiary Polyzoa. Geol. Mar/, dec. 



ii. vol. iii. pp. 522, 523. 

 Proposes the name Goniocladia in place of Carinella, formerly applied 

 to a new genus of Carboniferous Polyzoa, the latter being pre-occupied. 

 Gives the description by Prof. Busk, with a figure, of Memhranipora 

 Etheridgii (n. sp.), from the Post-Tertiary Carse Clays of the Raised 

 Eeach series of Scotland. H. A. X. 



]S"ote on the Fossils from the Glacial deposits of the North- 



west coast of the Island of Lewis, Outer Hebrides. Geol. May. 



dec. ii. vol. iii. pp. 552-555. 

 Gives lists of the fossils from deposits, partly stratified, partly un- 

 stratified. The fossils consist principally of Gastcropods and Lamelli- 

 branchs, with several Foraminifera, Balanus halanoides, and a Polyzocin 

 (Salicornaria sp.). Though several of the forms are of a northern type, 

 the only two thoroughly Arctic species are Astarte depressa and Pecten 

 Islandicus. Describes and figures certain peculiar burrows penetrating 

 a piece of the shell of Cyprina Islandica, which the Rev. A. M. Norman 

 believes to have been formed by fungi. 11. A. N.
