new variety, estefatn'ae, of C. arctispira, Pfr., is described and figured, and a 

 new species C. dispar, from Guatemala.

 I'Acad. Imp. d. Sci. St. Petersb., iQoi, T. xii., pp. i — 28, pi. i — iv. 

 The author returns to a further study of Psciidovennis, and confirms the 

 opinion expressed in 1899 that it is a mollusc. It is classed among the Nudi- 

 branchia, and is most nearly related to Eolis. A new species, P papillifera, is 

 described from Mytilcne, and the anatomy of that species and P. paradoxus 

 are described, and illustrated by four very beautiful plates.

 1902, Bd. viii, pp. 735—737, T. Ixvi, figs. 5—9. 



Dr. Thiele gives a description of this new species from Amboina, and a 

 short account of the anatomy.

 Proc. Linn. Soc. N.S.W., 1901, pp. 709 — 716, pis. xxxv — xx.xvi. 



The author describes and figures the protoconchs of eleven species of 

 Gasteropoda found in various bays in and around Port Jackson. The sug- 

 gestion is made that where no varix has been thrown up, it may be that the 

 mollusc has left no conchological record of the nepionic period. 



Keller, W. — Die Anatomie von Wjginiila gayi F'ischer. Zojl. Jahrb., Suppl. v, 

 1902, pp. 607—642, T. 18. 



The author has investigat'^d the anatomy of V. gayi, Fisch., on material 

 brought home by Prof. Plate from Chili. After a description of the external 

 features, and the structure of the integument, the pallial complex is described. 

 The kidney' is somewhat triangular in shape; the ureter is folded showing three 

 limbs, the third opening into the base of the lung. The author also gives a 

 corrected account of the kidney in V. uulleyi, Cllge. The alimentary canal 

 shows a well marked division into oesophagus, stomach, with cardiac and 

 pyloric portions, and a strong, muscular, true stomach. The "liver " is divided 

 into a fore-and hind-liver, the former consisting of eight lobes, and the latter of 

 two. The generative organs are of the usual type. 



The central nervous system is characterised by the extraordinary way in 

 which the cerebral, pedal and visceral ganglia approximate to one another, and 

 also with the small buccal ganglion. The nervous apparatus of the foot consists 

 of a thick network of anastomosing fibres in connection with the pedal nerves.

enie der Mollusken. Zeit. f. wiss. Zool., 1902, Bd. Ixxii, pp, 249 — 466, Tafn. 



xviii— xxvii u. 21 fign. 



The author, after an exhaustive survey of the anatomy and phylogeny of 



the Amphincura, concludes that the Solenogastres arc really a group of worms 



allied to the thread-worms (Gordiidac) and annelids, but, in the relation of 



the heart to the uterus, and in the possession of a rudimentary radula they 



approximate to the Mollusca, more especially to the Chitoiiidac.

 etc. Quart. Journ. Micro. Sci., 1902, vol. 46, pp. yy — 96, pi. 6, 

 In connection with studies upon the Gastropod kidney, the author here 

 gives an account of the relations of the kidneys in Haliotis, together with certain 

 suggestions concerning the kidney and reproductive organs of the Monoto- 

 cardia,
