18 COLLINGE : NOTES ON SLUGS AND SLUG-LIKE MOLLUSCS. 



The specimen I have examined has a label attached bearing the 

 following particulars : " Limax (Milax) umbrosns, Phil. Sicilien. — H. F." 



It was at once evident on first examination that this specimen was 

 very distinct from L. flams, and on dissecting it I had no hesitation in 

 referring it to the genus Amalia, Moq., as evidently was the opinion of 

 " H. F.," the writer of the label. T would further point out the very 

 jieculiar foot-sole which this species has, viz., two narrow lateral planes 

 marked with fine transverse lines, and two median planes, separated by 

 a zig-zag line thus WW, and differing from that of any other species 

 of Amalia with which I am acquainted. 



2.— On a species of Arion fpom New Zealand. 



Towards the end of 1S99, Mr. Henry Suter forwarded to me a small 

 collection of slugs from New Zealand, consisting chiefly of specimens of 

 the common species of Limax, Agriolimax, and Amalia, and a single 

 example of a species of Arion from Auckland. So far as I am aware 

 Arion fuscus, 0. F. Miill., is the only member of this genus which has 

 been found in New Zealand, and in spite of careful inquiry, I have as yet 

 been unable to refer the Auckland specimen to any known species. 

 From the external features 1 should say that it belongs to the subfuscus 

 group, although the mantle is small. The specimen (in alcohol) measures 

 13.5 millim. in length, and is of a luiiform light chocolate-brown colour ; 

 foot-sole slightly ligliter in colour antl smooth. 



3.— On the dispersal of Mieroparmarion, sp. 



1 have recently received from Mr. Arthur E. Shipley, three cxampbs of a 

 new species of Mieroparmarion, which were sent to him from Kew, 

 having been received there in some plants forwarded by Mr. K. Shelford, 

 of Sarawak, N.W. Borneo. 



In addition to affording a good example of the artificial distribution of 

 such animals, these particular slugs offer a further point of interest. On 

 teasing out the contents of the stomach of a specimen which had been 

 cut open, 1 found numerous bits of vegetable tissue, hypliae and spores of 

 fungi, bits of chitin and many chitinous hairs, and finally, an almost 

 perfect specimen of an ant. The latter, I sent to Mr. W. F. Kirby, of the 

 British Museum, who very kindly asked Col. C. T. Bingham to identify 

 it for me, and he writes that it is a specimen of Cremastogaster miri, 

 Forel, and that it is common in Borneo. 



The numerous hairs and bits of chitin in the stomach would lead 

 one to suppose,that these insects form a considerable item in the food of 

 this particular species. Whether they are eaten dead or alive, 1 cannot 

 say. 



I had previously received examples of this slug from Mr. Shelford, 

 which 1 hope to describe in detail later.
