148 THE ZOOLOGIST. 



whom some of the substance had been submitted for examination, had found 

 no blood-corpuscles therein, and considered it to be grease in a semi-fluid 

 condition, the nature of the colouring-matter being as yet undetermined. 

 Mr. Druce thought the substance exuded might be the excretion of the 

 larvae of some insect feeding upon the internal surface of the horn, and 

 suggested the examination of a section, if possible. 



Mr. Harting exhibited a drawing from life of a Klipspringer Antelope, 

 Oreotragus saltator, lately received (for the first time in this country) at the 

 Zoological Society's Gardens. He directed attention to the singular position 

 of the hoofs and the enlarged condition of the fetlocks, suggestive of injury 

 during capture. It was difficult to believe (as alleged) that this was the 

 normal condition of the animal, so very dissimilar to that of other species 

 allied to it. 



Mr. Thomas Christy exhibited several cases of Butterflies collected by 

 Mr. Horace Billington in Old Calabar, on which remarks were made 

 by Messrs. W. F. Kirby and H. Druce. 



Mr. B. D. Jackson, in directing attention to an English translation by 

 Mr. J. Lucas of that portion of Pehr Kalm's 'Travels' which relates to 

 England, remarked that few persons were aware that Kalm, a pupil of 

 Linnseus, had in 1748 spent six months in this country and had diligently 

 noted the plants which he met with Thus he had recorded no less than 

 sixty plants for Hertfordshire alone, deriving some of his information 

 from an examination of the contents of two haystacks in that county, — in 

 this way anticipating by more than a century one of the methods employed 

 by Sir John Lawes and Sir J. H. Gilbert, and by Prof. Fream. 



On behalf of Prof. Gustav Gilson, of Louvain, two papers entitled 

 11 Studies in Insect Morphology" were communicated by Prof. Howes. In 

 the first of these — " On Segmentally Disposed Thoracic Glands in the 

 larvae of Trichoptera" — the author found that in Limnophilus flavicomis 

 the prothoracic prominence gives exit to an underlying tubular gland. In 

 Phryganea grandis each thoracic sternum gives exit to a glandular apparatus 

 of the same category, the pro thorax alone developing a prominence. Passing 

 on to a consideration of the glands themselves, it was shown that in 

 Phryganea they are slightly monilated branching tubes of a paired nature, 

 which unite in the middle line. They are found to bear a cuticular lining, 

 and to secrete an " oily " fluid which Dr. Hanseval had found, on analysis, 

 to be identical with the secretion of the maxillary glands of Cossus. The 

 author gave reasons for regarding these glands as inherited structures, 

 preserved under the tubiculous habit, and not as organs newly acquired in 

 correlation with that. In discussing the homology of the glands, he 

 instituted comparisons with the " Bauchdnise" of certain non-tubiculous 

 caterpillars and the " salivary glands" of Peripatus; and concluded that 

 they are nephridial rather than coxal, pointing out that by their discovery
