24 JOURNAL OF MARINE ZOOLOGY AND MICROSCOPY. 



IMPORTANT NOTICE. 



The four microscopical preparations illustrated and described 

 in the preceding pages, form the first quarterly instalment of a series 

 of 14 subscription slides now in course of issue. There will be 

 included fine mounts of entire organisms, e.g., New Hydroids of great 

 beauty, Medusoids, Tomopteris, larval annelids (Polynoe, Nereis), 

 rare larval crustaceans, expanded Polyzoa, pelagic Tunicates (Salpa, 

 Doliolum), &c, also type slides of British Sponges, anemones and the 

 like. The remaining slides of the series will be treated in the same 

 detail as are the four which have received attention in the preceding 

 pages. 



The slides will almost entirely be new to our lists — but should 

 subscribers have a duplicate of any slide sent, we will willingly give 

 an opportunity of allowing another slide to be chosen in substitution. 



This opportunity will we think be required in only two instances, 

 viz. : Lucernaria and Plumularia. Several subscribers who have 

 these two slides, have requested us to include these two animals for 

 illustration and description in the pages of the Journal, so if any 

 subscriber having these will send a post-card naming another slide 

 which he may wish substituted, we will arrange accordingly. A list 

 of recent mounts will be found on the cover, and from among these a 

 suitable substitution will probably be found. 



The subscription, inclusive of the Journal and the 14 slides, 

 is 21/- post free. Sample sets will be sent on approval if desired. 

 Further particulars on application. The Journal may be had 

 separately, and will be supplied post free for 6d. per number, or 

 2/- per annum. Address : Sinel and Hornell, Biological Station, 

 Jersey.
