length, and again becoming so much shortened as to bring the sac which it 
carries on its summit almost in contact with the tentacle of the planoblast.

The Secretary read a report on the additions that had been made to the 
Society’s Menagerie during the month of November, amongst which special 
attention was called to a fine example of the King Penguin, Aptenodytes 
Pennanti, purchased November 14th. 
Mr. H. Seebohm exhibited, and made remarks on, a collection of birds 
made by Captain the Hon. G. C. Napier, in the Valley of the Atreck, near 
the south-east corner of the Caspian Sea. 
Mr. R. G. Wardlaw Ramsay exhibited a specimen of Pericrocotus 
flammeus, in an abnormal state of plumage, obtained on the Neilgherry 
Hills in Southern India. 
Mr. Sclater exhibited a small collection of birds from the island of 
Montserrat, West Indies, received from Mr. J. E. Sturge, of that island. 
This collection, though small, was of much interest, as nothing was previously 
known of the Ornithology of Montserrat. 
Mr. T. Jeffrey Parker read a paper on the intestinal spiral valve in the 
genus Raia. Mr. Parker showed that there were four types of valve 
exhibited in individuals of that genus, differing from one another in 
morphological characters, in the extent of absorption surface presented to 
the food, and in the resistance offered to the passage of food. 
A communication was read from the Marquis de Folin “ On the Mollusca 
of the ‘ Challenger’ Expedition of the genera Parastrophia, Watsonia and 
Cacum.” 
Prof. W. H. Flower read a communication on the cecum of the Red 
Wolf, Canis jubatus, in which it was shown that that animal differed from 
the majority of the Canide@ in possessing a very short and perfectly straight 
cecum. 
A communication was read from Mr. Edward Bartlett, containing a list 
of the mammals and birds collected by Mr. Thomas Waters in South-East 
Betsileo, Madagascar. The collection contained a new species of rodent 
belonging to the genus Nesomys, and two new species of birds of the genera 
Cypselus and Zapornia.
