many particulars are given as to the rates of growth 

 in Ccelenterates, Sponges, Flat and other Worms, Polyzoa, 

 Crustacea, Mollusca, Tunicates, and other marine groups. 

 Of practical importance is a short section dealing with the 

 rate of growth of Oyster spat during the first summer. The 

 particulars given, however, are only of a preliminary nature, 

 but since samples of these Oysters are being kept under 

 observation we may look forward to a fuller account later. 



In the same Journal 1 we note with pleasure a lengthy 

 and important " General Report on the Larval and Post- 

 Larval Teleosteans in Plymouth Waters." This paper, 

 which is by R. S. Clark, lately attached to the Scottish 

 Oceanographical Laboratory, is crowded with details con- 

 cerning the spawning, distribution of larval and post-larval 

 forms, and vertical distribution of the young of a large 

 number of fishes, representing no fewer than nineteen 

 families. Several figures accompany the report, which will 

 prove of much service to British ichthyologists. 



The Marine Biological Association of the West of 

 Scotland has issued the Annual Report for 191 3, from 

 which we are pleased to notice that much good work 

 continues to be done at Millport. During the year eleven 

 species have been recorded as new to the area investigated, 

 while short notices are given of several papers which have 

 appeared during the year as the result, wholly or in part, 

 of work done in the station. 



An account of the love-song, and of the prolonged, 

 patient, and ineffective attempts of several males of a familiar 

 Grasshopper, Gomphocerus maculatus, to woo an unwilling 

 female, is given in the Entomologist by S. E. Brock, from 

 observations made at Kirkliston ; 2 and in the same magazine 

 (p. 80) is to be found a careful description of the larval 

 development of the common Dragon-Fly, Sympetrum strio- 

 latum. With the voracity of the nymphs everyone is familiar, 

 but it is amazing, nevertheless, to find that although they were 

 fed on bloodworms almost daily, they " would sometimes eat 

 as many as eight in succession, though each was as long as 

 the nymph itself." A detailed study of the development of
