tion, as suggested by the abundance of sarcode and the scarcity 
of gemmule or statoblasts; the single small group of these 
organisms alone rewarding a careful search through the whole 
mass of material sufficed to fix its generic position—Zdward

A Hermapuropitic Cras.—While conducting an exercise in 
zodlogy a short time ago using the common crab (Callinectes 
hastatus) I noticed one specimen having an abdomen intermediate 
in form between that of the normal male and female specimens. 
I at once inferred that it might be a case of hermaphroditism, 
which I think it is. The abdomen is triangular and except the 
terminal portion or telson is devoid of joints; the joints of the 
normal female abdomen being represented by indistinct lines. 
The abdomen was firmly imbedded in the plastron, it being evi- 
dently not within thé animal’s power to “open” it. 
dominal appendages resemble in general those of the female, al- 
though much more attenuated and having an undeveloped appear- 
ance. The fifth pair of pereiopods lack the reproductive orifice 
in the basal joint found in the male; nor is the first pair of pleo- 
pods modified into copulating organs. The two little hooks 
fastening the abdomen into its groove are present ; while there are 
only impressions representing the opening through the female 
plastrons for the expulsion of the eggs. en examined the in- 
ternal organs were not in condition for a minute examination, still 
it is evident that neither male nor female organs were normally 
developed, as these organs were distinct in other specimens in 
similar condition, while they could not be found in this one.—A.

Discovery OF BLIND FIsHES IN CALIFoRNIA.—At Santa Clara 
College in the San José valley is a flowing artesian well 170 feet 
eep, from which are discharged sightless fishes, from one to two 
inches long. I shall make arrangements to send specimens of 
these to Professor Baird, United States Fish Commissioner, who 
informs me that he has eighteen varieties or species of blind fishes 
from Eastern artesian wells; none have been secured from this 
coast.— F. D. Caton. 
Tue Mute DEER IN DomesticaTion.—I find here three speci- 
mens of Cervus macrotis var. californicus in domestication, which 
_have given me an opportunity of observing them not hitherto en- 
joyed. This variety of the mule deer I first discovered at Santa Bar- 
bara in 1875 and spent nearly a week in the mountains and pro- 
cured specimens for mounting, which I sent to the Smithsonian 
Institution, and I first described them in The Antelope and Deer of 
America, p. 95. While they are a true Macrotis, the variety is 
very distinct, the enormous ear which induced Lewis and Clark, 
who first discovered them, to call them the mule deer is common 
‘to both varieties, but the ear on this new variety I now find is not
