Limax avhonim has a curious habit of burying itself in a kind of open 

 trough to which it frequently retires, continuing there at rest for a 

 whole day at a time. 



Limn,x flaviis. — The eggs of this species are very beautiful when 

 first deposited, they are oval, 7 mm. in length, with a small point at 

 each end as if they had been connected by a filament, which had 

 been broken, colorless and as transparent as a drop of water. These 

 eggs, 16 in number, were deposited beneath a small stone on the 19th 

 of July, 1888, about half of them produced young slugs on the 15th of 

 August, these were very pale yellow and almost transparent, measuring 

 II mm. when fully extended ; ten days later they had reached 18 mm. 

 and become yellow-green in colour. These slugs delight in frequenting 

 cellars, and I have found their eggs in damp corners within the house. 



Limax laevis. —This species deposits its eggs singly for the most 

 part, occasionally in twos or threes. They are oval, usually 2.8 mm. 

 by 1.8 mm., colorless, perfectly translucent. I have seen an egg only 

 2 mm. in length. They have been deposited on the ground, on their 

 food, and on the glass under which they were confined. The soil 

 contained in the pots in which L. laevis is confined should be kept very 

 moist, a good plan is to let them stand in saucers containing an inch 

 or two of water. 



Helix arbiistorum.--^^ Found 8 eggs, round, semi-transparent, various 

 shades of yellow." 



Helix cantiana. — "Hatched, young, very minute, i mm." Eggs not 

 described. 



Helix vergata. — "Deposited eggs just below the surface, three were 

 above, white, slightly translucent, diameter 1.8 mm., one very small, 

 I.I mm., and yellowish." 



Zonites nitidtilus. — "Found eggs scattered over the surface, 1.5 mm., 

 white with opaque calcareous shell. 



The following notes illustrate the variations in colour which some of 

 our slugs undergo in their youthful stages. In the last half of July I 

 found a small Avion concerning which I entered the following 

 description and remarks in my notebook: "Drab with pencil lines 

 sides and round shield, has a white sole and I have not seen it so 

 greatly extended as those from the "Decoy." The latter part of my 

 note refers to a rather large capture of A . minimus, some of which at 

 first glance this slug resembled. On the 24th of September I entered
