On the Morphology of the Ophiuroidea. 
By the Rey. Aurrep Mere Norman. 
The structure of the skeleton in these star-fishes was commented upon with 
especial reference to certain morphological points which were found to be of great 
value in the elucidation of species, but which had not hitherto been attended to 
by British naturalists. The following recent additicns to our fauna were men- 
tioned :—Ophiura Sarsii (Liitken), Ophiwra squamosa (Liitken), Ophiwra affinis 
(Liitken) (synonymous with O. Normani, Hodge), Amphiwra Chiajii (Forbes), 
Ophiopeltis securigera (Duben and Koren), Asteronya Lovéni (M. and T.); and the 
specific characters of the several forms were pointed out. 
On British Holothuriade with reference to new Species. 
By the Re¥. A. M. Norman. 
The object of this paper was to bring together information which is scattered 
through many publications on the naked Echinodermata of Great Britain. Since 
the publication of the late Professor Forbes’s work, several species of interest have 
been added to our fauna—namely, Cucumaria elongata (Duben and Koren), Thyone 
raphanus (Duben and Koren), Psolus sguamata (Duben and Koren), Holothuria 
nigra (Peach), and Synapta inherens (Miller), The author described three new 
species: Psolinus pusillus, taken by My. Alder and Mr. G. Hodge on the coast of 
urham; Zhyone floccosa, from Cornwall; and Synapta tenera, dredged by Mr. D. 
Robertson in the Clyde district. Attention was especially called to the value of 
the examination of the dermal spicula or calcareous plates in determining specific 
character in this order. These plates are generally profusely distributed in the skin 
of the Holothuroidea, and are also found in the feet and tentacles, 
On the Occurrence of the Sperm Whale (Physeter macrocephalus) near 
Wick, N. B. By C. W. Pracu. 
It was found floating dead on the west side of this county (Caithness) in August 
1863, and towed into a small cove near Reay. Its length was between 60 and 70 
feet, and it yielded about 1620 gallons of blubber, spermaceti, and oil. Each lower 
jaw had about 22 teeth. 
Captain Macdonald, of Sandside House, purchased it of the Receiver of Wreck, 
and under his superintendence the skeleton has been carefully preserved. The 
authorities of the British Museum have since purchased it for that institution. 
Notice of a Monstrosity in a Whiting. By CO. W. Ross. 
The fish, which was exhibited to the Section, had three eyes, two in their natu- 
ral position, and one between the two. He believed lusus nature among fish very 
rare, a great authority upon the subject mentioning only two such malformations 
—in one case a contraction of the upper jaw, and in the other an elongation of the 
lower. As a proof of the rarity of these occurrences, it was only necessary to bear 
in mind that, amongst the thousands of whiting brought in, and the hundreds of 
thousands of mackerel and herring, this was the only instance of the kind of which 
there was any note. 
On the Generic Characters furnished by the different Modes of mining Leaves 
adopted by the Larve of Micro-Lepidoptera. By H. T. Sraryton, 
There are no less than 20 different genera of the Tineina of which the laryz 
mine beneath the skins of the leaves of plants; some of these always remain 
miners, having no power of quitting their mine to enter a fresh one; some 
even change to the pupa state within the mine, but the greater number issue 
from their mines when full-fed, some before doing so cut out flat oval cases from
