pected from the position of Dublin, half-way between Ardglass Head and 

 Carnsore Point, between which two points the trne eastern marine district 

 of Ireland lies, the great southern province prevailing below the latter 

 point. The new Crangon most probably belongs to either the Celtic or 

 British types, as otherwise the absence from British lists of this con- p 

 spicuous species is not very creditable to the observative powers of our 

 collectors. 



Numerous examples of the several species described illustrated 

 these remarks. 



Bev. Professor Haughton corroborated from observation Dr. Kinahan's 

 surmise with regard to Carnsore Point. The shells to the south are very 

 distinct in their types, from those occurring even a very short distance 

 north of this point. 



Dr. William Prazer next submitted the following, as the result of 

 his investigations regarding the Pungi presented at the former meeting 

 by Gr. Y. Du Noyer, Esq., from Major O'Connor, and which he had been 

 requested to examine and report on. 



REMARKS UPON SPECIMENS OF FUNGI, OBTAINED ADHERING TO OLD TREES 

 UNDER A BOG NEAR TRALEE. 



These specimens of fungi were, I understand, obtained adhering to oak 

 timber which lay upon gravelly clay, and was covered by about thirteen 

 feet of bog. 



They are evidently specimens of "Polypoid," a class of fungi cha- 

 racterized by the presence of innumerable " subrotund pores separated 

 by their dissepiments, and having the hymenium concrete with the sub- 

 stance of the pileus;" and I have also no difficulty in referring them to the 

 second subdivision of this class, namely, those furnished with minute, 

 subrotund (not angular) , pores. That they were ' ' stemless and perennial, ' ' 

 their numerous layers of growth, the results of successive seasons of 

 development, amply demonstrated. Thus, out of forty-five species of 

 Polyporus described in the Plora Britannica, I am restricted to about 

 thirteen, to which only do these specimens present any analogy, and of 

 these I have little difficulty in deciding that they most closely resemble 

 P. igniarus, or the hard Amadou, of which I exhibit a specimen which 

 had been growing for some years past on an old decaying plum tree, and 

 although at first sight it appears to be very different in external form 

 from the specimens from Tralee, I am pretty certain, at least, as to their 

 close relationship. The difference between them in form is easily explained 

 by the mode of attachment and development in both cases. The recent 

 ones adhering to a great trunk, and creeping along its side in successive 

 waves of growth; and the older ones closely resembling in shape a 

 " horse-hoof," to which Mr. Berkely compares them, and which was 

 probably due to their more erect growth on a fallen log of timber. The 

 detection of undoubted remains of fungi in a semi-fossilized state is, I 

 believe, extremely rare, and I am disposed to think that the fact is, as 

 has been stated by Lindley, not to be so much attributed to their positive
