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 Phocena 
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. 
The Stuffed Whale in the Swedish Museum. 
In reply to my inquiry, Professor Lilljeborg observes, ‘ Vous 
m’avez prié de vous instruire de la méthode au moyen de laquelle la 
Baleenoptére du M. Malm a été conservée. La peau de Ja méme a 
été divisée en plusieurs morceaux, et a été depuis étendue sur un 
modeéle‘de bois exactement de la méme forme et grandeur que de l’ani- 
mal lui-méme. L’épiderme est conservé sur la peau, et il est pour- 
tant trés-peu lésé. La couche graisseuse de la peau a sans doute 
été trés-menue, autrement |’ épiderme en se desséchant aurait été plus 
plein de fentes et de rides quil ne présente maintenant.” —J.E. Gray. 
Observations on the Reproduction of the Cecidomyidee. 
By F. Mrertnert. 
In an article ‘On the Orgin of the Germs in the Larvee of Mias- 
tor”? (Naturhist. Tidsskr. ser. 3. vol. ii.) I maintain, in opposition 
to the opinion of M. Pagenstecher, that the germs of the larvee ori- 
ginate in the adipose tissue. In another paper, entitled “A few 
more words on Miastor,” 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 imsect from 
the larva referred to by MM. Pagenstecher and Leuckart, to which 
I give the following name and diagnosis :— 
Oxicarces. Haustellum nullum; palpi nulli. Tarsi 2-articulati. 
Antenne moniliformes, 1l-articulate. Ale costis binis vel ternis 
abbreviatis, evanescentibus. 
O. paradoxus. Ochraceus, capite atque mesonoto nigrescentibus. 
Femina: antennz 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
