found all summer within ten to twenty miles of the coast. Ata place near 
Oakland where the kitchen-refuse of part of the town is dumped, near a 
swampy spot, they come out in hundreds to feed on the rotten vegetables, 
etc., emerging about 4 p.m. up to June, when fogs prevailed, but not until 
sunset in August. A few L. campestris inhabit the same spot, but remain in 
the wet grass only. 
A. niger Cp. This, described with P. Andersonii, I have since found 
once near Cypress Point, Monterey, as well as in several places within the 
range given before. Near Oakland it does not appear until the ground is well 
soaked with rain, about November, and deposits its eggs in December to 
February. It does not occur in gardens, but in uncultivated oak-groves on 
clay lands. 
“A. Hemphilli W. G. Binn., lately described from Niles Station, 
Alameda Co., seems externally only like a pale var. of A. niger. 
Limax (Amalia) Hewstoni Cp. In our Proceedings IV, p. 151, 
1871, I referred to this as ‘‘another new species of Limacide,’’ being uncer- 
tain whether it might not be imported, as I found it only in San Francisco. 
It certainly agrees nearly with the too brief description of L. Sandwichensis 
as well as the figure, in Voyage of the Bonite, II, p. 497, Pl. 28, f. 8, but 
comparison of living specimens will be necessary. Mr. Binney in Ann. N. Y, 
Lye. XI, 22, states that specimens of an Amalia were sent to him by Mr. 
Hemphill from Los Angeles, and though differing in its dentition, thinks it 
indicates that the genus is native to California. I am more inclined to think 
some species has also been introduced there with orange trees, grape vines, or 
otherwise. 
My reason is, that I have searched carefully for these animals in Southern 
California since 1871, and found only Limax campestris, which is common 
near San Buenaventura, and occurs south to San Juan Capistrano, while I 
found none in the mountains or valleys near San Diego, and no other one at 
Los Angeles. ; 
This species has apparently succeeded in establishing itself in spots on the 
east side of 8. F. Bay, where the climate is much drier than in the city. I 
have found it only in one very damp garden in Oakland, and in some 12 miles 
east of there, while outside of cultivated gardens, even where always moist, 
it does not occur. 
Alexia (myosotis var.?) setifer Cp. Since my first notice of this 
species, it has been nearly exterminated in Mission Creek, by street cross- 
ings and obstructing the tidal flow, so that I have lately found it only in 
one spot near the mouth. It may, however, remain more scattered in 
Mission Bay, though so exceedingly tender that it has died in every other 
locality where I have tried to colonize it. The name givenin Vol. V, p. 172, 
as ‘‘ Melampus ciliatus’’ should be Auricula ciliata Moricand. 
Ancylus crassus Hald? A specimen received from Humboldt River, 
Nev., by Dr. Yates, appears to be a thin variety of this, approaching 
‘‘ A, Kootaniensis’’ Baird, and thus counecting the latter with former, as I 
doubtfully placed them in these Proceedings, IV, 101, 1870.
