been compared to similar markings in certain Brachiopods. So among 

 the latter group do we find forms attached, as in Thecidium, and some 

 species of Productus ; and generally the articulate Brachiopods might 

 be compared to such forms as Lepralia, while on the other hand, such 

 genera as Pedicellina, with its long, pliant, and muscular stalk, or 

 Loxosoma, with a stalk highly retractile, may be compared to Lingula. 

 The limits or intentions of this jiaper will not allow any considerations 

 regarding the relations of the Brachiopods with the other groups of the 

 animal kingdom. " I have elsewhere expressed my belief that they 

 are true articulates, having nearer affinities with the Vermes ; and in 

 view of the above relations of the Brachiopods with the Polyzoa, it is 

 interesting to remark that Leuckart has for a long time placed the 

 Polyzoa with the Vermes, and in a new edition of the ' Outlines of Com- 

 parative Anatomy' Professor Carl Gegenbaui- removes the Polyzoa 

 from the MoUusca, and associates them with the Vermes." 



NOTES AND MEMOEANDA. 



The 'Archives de Zoologie experimentale et generale.'— The 

 first number of this periodical has, we believe, appeared. It is under 

 the editorshij) of M. H. Lacaze-Duthiers, and the subscription list 

 is 35 francs a year. It is to deal with general zoology, supported 

 by the precise laws of morphology, deduced from the most minute 

 histological inquiries, demonstrated by a long and continued study 

 of evolution, and submitted to the control of experience. In a word, 

 it is to deal with Experimental Zoology. It will be a quarterly pub- 

 lication, and its Nos. will ajipear in January, April, July, and October. 

 Each number will contain from eight to ten sheets of matter, and five 

 or six plates, done either on copper or lithographed, and occasionally 

 coloured. It will have a si^ecial part for the review of foreign works. 

 A better editor than M. Lacaze-Duthiers could not have been chosen 

 for the serial. 



Field Club Prizes. — The Early Closing Association announces, 

 through Mr. Henry Walker, their Secretary, that they intend giving 

 prizes, among other subjects in microscopy, to London naturalists, &c. 

 We regret to see that the Royal Microscopical Society is excluded 

 from the list of competing bodies. In answer to a communication 

 from us, Mr. Walker replied that he would see whether the Royal 

 Microscopical Society should not be included along with the various 

 other microscoj)ical societies, but as we have not heard from Mr. 

 Walker for some time, we fear his efforts were unavailing. The 

 Countess of Ducie is the lady who has given the funds for the esta- 

 blishment of the prizes, which are as follow : — 5Z. 5s. for the best 

 List of the Ponds and other aquatic resorts, within fifteen miles of 

 London, and the Mierozoa found in them, in the twelve months
