Flora Anglica about the beginning of this century and named 
Conferva coccinea. Afterwards C. Agardh placed it in the genus 
Dasya. 
I am indebted to Mrs. B. C. Winston of Pacific Grove for 
calling my attention to it, and for a specimen. It is by no means 
abundant, but serves as an example of the curious fact that 
many European Algze which do not appear on our Atlantic 
Coast are found on our Pacific Coast. 
ON THE OCCURRENCE OF NYCTINOMUS MOHAVEN- 
SIS IN THE SANTA CLARA VALLEY. 
BY J. M. STOWELL. 
In the early 8 of last February the writer was informed 
by Mr. Edward M. Ebrhorn, Horticultural Commissioner of 
Santa Clara Codatys that the Court-house in San Jose was in-. 
fested by large numbers of bats, which were taking refuge 
behind the iron window-shutters and disturbing the course of 
Justice by their constant chattering. A visit to the Court-house 
February 27 showed that the state of affairs had not been 
exaggerated. On opening the leaves of one of the shutters, the 
bats were found thickly clustered in the darker recesses: ‘They 
seemed extraordinarily clumsy and made little attempt to escape, 
only a few fluttering away after having fallen from their perch. 
About seventy specimens were procured and prove to be repre- 
sentatives of Nyctinomus mohavensis, with Merriam’s rather 
meagre description of which (N. A. Fauna, 2, p. 25) they en- 
tirely agree. This species was described apparently from a 
single specimen procured at Fort Mohave, Arizona, March 8, 
' 1889, since which no additional specimens seem to have been 
recorded. The present discovery of the species in the Santa 
Clara Valley gives a notable extension to its range. 
We have been unable to compare NV. mohavensis with the 
closely-allied WV. brasiliensis, and Dr: Merriam neglects to point 
out the characters distinguishing the two species. Dr. Harrison 
Allen informs us that he considers both WV. mohavensis and JN. 
Jemorosaccus as at best geographical races of NV. brasiliensis.
