18 NOTICES OF SERIALS. 



p. 331-341. (Girard) On the viviparous fishes of the west coast of North 

 America — p. 342-354. Both extracts from Proceedings of Philadelphia Academy : 

 translated by the Editor. (Reissig) On the mode in which the Tachina? effect 

 their escape out of the puparia, and out of the closed cavities in which they are 

 often found — p. 189-196. The author dismisses entirely the idea of any liquid 

 solvent being used for this end, and considers the force as entirely mechanical, 

 the head, swelled into a globe by fluid pumped into it, acting as a hydraulic press, 

 assisted by the points of support which the bristles of the abdomen afford. 

 (Krohn) On the heart and circulation in the Pycnogonidse ; with a figure — p. 6-8. 

 The circulation was observed by Beneden in the legs of Nymphon, but he could 

 not find the heart. This organ, the existence of which has been generally ne- 

 gatived by Quatrefages, was demonstrated by Zenker in Nymphon pallipes. A 

 more particular account of its structure, and of the phenomena of circulation, are 

 given in the present essay. (Steenstrup) Observations on the genera Pachyb- 

 della Dies., and Peltogaster Rathke, parasites on the abdomen of Crustacea ; ex- 

 tract from the Proceedings of the Danish Society of Science, a.d. 1854; trans- 

 lated by Creplin — p. 15-29. Steenstrup considers both these forms to be crus- 

 tacean, and shows that they are not hermaphrodites, but leaves their place in the 

 class doubtful. (Same) Supplement to the preceding article — p. 62. (Zad- 

 dach) Holopedium gibberum a new form of the Branchiopoda ; with two plates — 

 p. 159-188. QGrube) Descriptions ofnew or little known Annelida, with three plates

 Helminthes and marine worms ; with two plates — p. 137-158. (Leuckart) On the 

 young of some Annelida, a contribution to Embryology ; with a plate — p. 63-80.

 dii. Malacoceros longirostris Quatrefages Mag. Zool., a.d. 1843, not separated 

 from Nerine, the eyes often becoming obsolete in the mature state of these 

 worms. (Peters) On the g. Bdella Sav. and the Annelida observed in Mozam- 

 bique — p. 35-42. Calymmatops n. g. of Terebellse, C. granulatus n. sp., and ten 

 new species of other genera. (Troschel) Two new Heteropoda, Firolella gra- 

 cilis and vigilans, from Messina, with a plate — p. 298-311. (Krohn) Supplement to 

 the essay on Echinospira diaphana , see the Archives for 1853 ; with figures — p.
