Names of Ammonites. — Several preoccupied generic names have lately been 

 proposed for ammonites, as follows : — 



(i.) Plafytes, Mojsisovics, Abh. Geol. Keichsanst., vi, Abtti. i, p. 332, not of Guenee, 

 1845 ; this may be called Protoplatytcs, type P. iiegUxhis (Platytes ne^lectiis, Mojs.). 



(2.) Canavaria, Buckman, Emend. Ammonite Nomencl., IQ02, not of Oppenheim, 

 1899 ; this has been changed by Cossmann to Canavariwras. 



(3.) Walkcria, Buckman, t.c, not of Desvoidy, 1863, etc. 



(4.) Braitnsia, Buckman, t.c-, not of Kriechbaumer, 1894. 



(5.) Deltoccras, Buckman, t.c, not of Hyatt, 1894.

Continuing the account of the genus Acliatina, Lamarck, the sub-genus Lcptocala, 

 Ancey, is dealt with, also the genera Coclilitonin, Fer., Pilsbry, and Arcliacluitiiin

Trans. Liim. Soc. Lend., 1904, vol. i.v, pp. 269 — 290, pis. 15 — 17. 



The affinities of the Docoglossa are difficult to trace on account of the antiquity of 

 the group. Dr. Fleure, however, after a valuable study of the group, comes to the 

 conclusion that we are only justified in hinting that they and the Bcllcrofliontacca are 

 two of the earliest off-shoots from the Gastropod stem. 



In this paper the common ancestor of the Prosobranch Gastropods ; the foot and 

 edge of shell, visceral hump, branchial cavity and heart, and consolidation of the 

 visceral mass in the Docoglossa are discussed, and a valuable summary of Docoglossan 

 evolution and aflinities given.

Murdoch, R. — On the Anatomy of Paryphaitta fiiniosa, Tenison-Woods. Trans. 



N. Z. Inst., 1904, vol. xxxvi, pp. 156 — 191, pi. vi. 



The specimen upon which the author worked was collected at Mount Faircll, 

 north-west Tasmania, and is one of the rarest members of the genus. Its general 

 anatomy does not appear to present any important differences, except in the form of 

 attachment of the buccal-mass retractor.

Dr. Nierstrasz in describing the Chitons of this Expedition has coniined himself 

 to the systematic side, and a description of the morphology of the shell. That the 

 work is well done the author's name is a sufficient guarantee.
