finely denticulated near the end ;" so that it appears to be the same as 

 the species, described by Pliny and figured by Camper, that we have 

 in the Thames, and which I described under the name of Phoccena 

 tuberculifera. In the last edition of the 'Catalogue' (p. 402) I 

 stated that the species without the spines on the dorsal fin appears to 

 be very rare ; and it is doubtful if it is a distinct form, and if my 

 name will not have to sink into a synonym.

In reply to my inquiry, Professor Lilljeborg observes, " Vous 

 m'avez prie de vous instruire de la methode au moyen de laquelle la 

 Balsenoptere du M. Malm a ete conservee. La peau de la meme a 

 ete divisee en plusieurs morceaux, et a ete depuis etendue sur un 

 modele de bois exactement de la meme forme et grandeur que de I'ani- 

 mal lui-meme. L'epiderme est conserve sur la peau, et il est pour- 

 tant tres-peu lese. La couche graisseuse de la peau a sans doute 

 ete tres-menue, autrement l'epiderme en se dessechant aurait ete plus 

 plein de fentes et de rides qu'il ne presente maintenant." — J.E. Gray. 



Observations on the Reproduction of the Cecidomyidse. 

 By F. Meinert. 



In an article " On the Orgin of the Germs in the Larvae of Mias- 

 tor " (Naturhist. Tidsskr. ser. 3. vol. iii.) I maintain, in opposition 

 to the opinion of M. Pagenstecher, that the germs of the larvae ori- 

 ginate in the adipose tissue. In another paper, entitled " A few 

 more words on Miasfor," after some remarks upon the formation of 

 germs in another Cecidomyide larva, and on the formation and de- 

 velopment of the ovum in animals in general, I more particularly 

 indicate the relations of the germs to the adipose tissue. Here it 

 must be remarked that we have to do with two different forms, spe- 

 cies of two genera differing widely from each other, which have been 

 the subjects of investigations made by different authors. I have 

 been fortunate enough to be able to examine both forms ; and as I 

 was the first to classify the Cecidomyide examined by M. "Wagner 

 {Miastor), I have also succeeded in rearing the perfect insect from 

 the larva referred to by MM. Pagenstecher and Leuckart, to which 

 I give the following name and diagnosis : — 



Oligarces. Haustellum nullum ; palpi nuUi. Tarsi 2-articulati. 

 Antennae moniliformes, 11-articulatae. Alae costis binis vel ternis 

 abbreviatis, evanescentibus. 



O. paradoxus. Ochraceus, capite atque mesonoto nigrescentibus. 

 Femina : antennae corpore quadruplo breviores. Ovipositor brevis- 

 simus. Long. 1-25-1 '5 millim. Larva habitat sub cortice populi 

 gregatim. 



The cells which become developed into ova and germs, are usually 

 in connexion with the adipose tissue, of which they form part ; but 

 whilst this union persists for a certain time in Miastor (Wagner's
