Species 2. (Fig 24, 2c, Mus. Jardin des Plantes, Paris.) 
TEREBRATULA (WALDHEIMIA) DILATATA. Since the 
publication of the first four Plates of this Monograph I 
have been favoured by Professor Valenciennes, the esteemed 
pupil and successor of Lamarck, and, it should be added, 
at the friendly suggestion of Professor Milne-Edwards, 
with the original type of this and the following species. 
There has been no authentic identification in this country 
of the 7. dilatata and globosa of the ‘ Animaux sans Ver- 
tébres,’ and it is with much pleasure that I am able to 
give figures of the original specimens. It happens that 
they were named and described more than forty years ago 
by M. Valenciennes himself for Lamarck when that dis- 
tinguished naturalist, whose name commands our utmost 
sympathy and respect, commenced to be afflicted with 
blindness. ‘Ce sont les exemplaires originaux,” says M. 
Valenciennes in his letter to me, ‘‘ de mon travail sur les 
mollusques, et peut-tre mon premier sur les animaux, car 
il date de 1819.” 
that the authority attached to the names of these species 
should be, not Lam., but Val. apud Lam. The inscription 
of M. Valenciennes on the back of the tablet is as fol- 
lows :—‘‘ Exemplaire décrit en 1819 lorsque j’ai fait la 
monographie du genre Terebratule de Lamarck ; déja était 
aveugle. C’est la coquille de la collection de M. Dufresne, 
lequel a donné cette coquille au Muséum, en échange 
d’autres espéces. C'est done l’espece que j’ai nommée 
Terebratula dilatata, Val. apud Lam.” ‘The shell agrees 
precisely with that already figured for the species at Plate 
IL. from the collection of Mr. Metcalfe, but it is of still 
larger size. 
It is therefore due to M. Valenciennes 
Species 3. (Fig. 3d, 3e, Mus. Jardin des Plantes, Paris.) 
TEREBRATULA (WALDHEIMIA) GLOBOsA. I was much 
eratified, on receiving this shell, the original specimen de- 
scribed and named by Valenciennes and so clumsily figured 
in the ‘ Encyclopédie Méthodique,’ to find that I was right 
in having assigned to the species the well-known 7. Cali- 
fornica, Koch. Though not uncommon in collections, it 
had never occurred to writers on Terebratule (the latest 
being Mr. Davidson and Dr. Gray) that this species was 
A com- 
parison of the original type removes all doubt on the sub- 
ject, and the species may henceforth be known by the name 
inscribed on the French tablet, “Zerebratula (Waldheimia) 
globosa, Val. apud Lam. Anim. sans vert. vol. v. 1819; 
Enc. Méth. pl. 239. f. 2.” 
the 7. globosa of the ‘ Animaux sans vertcbres.’ 
Species 23. (Fig. 23a, 4, c, Mus. Jardin des Plantes, 
Paris.) 
TEREBRATULA PHYSEMA. Ter, testdé late globosd, tenut- 
culd, valdé inflata, sordidé fulvescente-albd, rostro 
amplo, modicé producto, subtus utringue excavato-de- 
presso, foramine ampliter evoso, deltidio subpartito, 
radiatim rudé sulcato ; valvis latis, levibus, obsolete 
malleatis, vie flewuosis, lineis incrementi versus margi- 
nem subrudibus ; apophyse (dirupta). 
THE INFLATED TEREBRATULA. Shell broadly globose, 
rather thin, very much inflated, dead fulvous-white, 
beak large, moderately produced, excavately depressed 
beneath on either side, foramen largely eroded, del- 
tidium slightly divided, radiately rudely grooved ; 
valves broad, smooth, obsoletely malleated, scarcely 
flexuous, lines of growth somewhat rude towards the 
margin; apophysis (broken away). 
VALENCIENNES, MS. in Mus. Jardin des Plantes, Paris. 
Hab. Coquimbo; Gaudichaud. 
This fine shell, belonging to the collection of the Mu- 
seum of the Jardin des Plantes, was collected by M. Gau- 
dichaud in 1833 at Coquimbo, and had been regarded as 
a TY. dilatata. M. Valenciennes, when selecting for me 
the specimens figured in this Plate, observed that it differed 
from that species, and named it 7. physema, with the fol- 
lowing remark :—* Grande et belle espéce de Terebratule 
(Waldheimia) confondue avec mon 7. dilatata, mais bien 
distincte, rapportée de Coquimbo en 1833 par M. Gaudi- 
chaud, et donnée par lui a M. Férussac. Achetée en 1837 
avec la collection.” 
It would be satisfactory if the species could be confirmed 
by the discovery of further specimens. It is intermediate 
in its characters between 7’. dilatatw and globosa, inclining 
rather to the latter species, of which it may prove to be a 
colossal broadly inflated variety.
