into a flat, round surface ; tubes projecting from the upper part of 

 the circumference ; centre nearly plane." 



Tubulipora penicillata? Turton's Lin. vol. iv. p. 615. 



" Hab. On shells and stones, and shells from deep water; com- 

 mon from the Eddystone Lighthouse to the Deadman Point. 



" It is calcareous and about a quarter of an inch in height; the 

 upper portion is expanded into a flat head, having on its superior 

 surface one or two rows of projecting tubes round the circumference ; 

 the centre is either plain or marked with a few irregular cells. The 

 cells are distant from each other, with slightly oblique unarmed aper- 

 tures. The under surface of the head is furrowed without cells, and 

 sloped into the footstalk." 



Flustra Peachii. 



Spec. Char. "Encrusting; cells radiating; apertures oval, un- 

 armed, with two punctures at each extremity. 



Hab. " On dead muscle and oyster shells, in the Fowey River, 

 off the Deadman Point : common. 



" Encrusting, membrano-calcareous ; cells ovoid, having their 

 longest diameter in the axis of growth ; at each extremity two mi- 

 nute apertures ; apertures even and unarmed. The cells, which have 

 a radiating distribution, appear somewhat confused from their radia- 

 ting from so many points and intermingling with each other. 



" This species was first found by Mr. Peach of Gowan in the 

 Fowey River ; since that time, in company with him, I have found it 

 abundantly encrusting almost every cell dredged up from Mixtow to 

 the mouth of the river. I have since found it in deep water west of 

 the Eddystone and nine leagues south of the Deadman. Not being 

 able to refer this to any described species, and having submitted it 

 to a gentleman well versed in the subject, who has pronounced it 

 new, I beg to give it the name of its discoverer." 



From an examination of Mr. Couch's paper it is evident, as might 

 have been looked for from the rocky nature of the coast, that the 

 calcareous species of zoophytes are particularly abundant on the 

 Cornish shore.

March 3, 1842. — M. Miiller read a notice on some Pathologico- 

 Anatomical Observations on Parasitical Forms made during a journey 

 in Sweden in company with M. Retzius. 



When occupied last August in Bohuslan in dissecting different sea 

 animals, MM. Miiller and Retzius had occasion to examine a dorse 

 (GadusCallarias) with a lean tail, which, according to the statement of 

 the fishermen, was not eatable on account of sickness. The seat of the 

 disease was the natatory bladder, in which was found a considerable 

 quantity of a yellowish smeary matter without smell. Seen under 

 the microscope it appeared of a very peculiar nature, containing
