ADDITIONAL REMARKS ON WEST INDIAN 
GYRINIDZE 
By Georg Ochs 
Frankfurt a. Main, Germany 
In 1924 (American Museum Novitates, No. 125) I pub- 
lished a paper on West Indian Gyrinidse and at that time 
believed that our knowledge of the family in that area was 
pretty complete. Recently, however, through the kindness 
of Dr. P. J. Darlington, Jr., I have studied a large collection 
of these beetles from the Antilles and Bahamas in the 
Museum of Comparative Zoology at Harvard College, Cam- 
bridge, Mass., and to my great surprise have found four new 
forms (two species, one variety and one form) from Cuba 
and Haiti. Moreover, several new records can be added for 
different species on the different islands. 
I take this opportunity of offering my sincere thanks to 
Dr. Darlington for his kindness in enabling me to work on 
this interesting material. 
Gyrinus rugifer Reg.
