NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 125 



The following species of Lysidice have been reported from the West- 

 ern Hemisphere. 



1. L. americana Verrill (1873, p. 508) from Massachusetts. 



2. L. collaris Grube, reported from French Guiana by Fauvel (1919, 

 p. 477) and from the eastern tropical Pacific by Monro ( 1933, p. 69) . 



3. L. ninetta Audouin and Edwards, p. 125. 



4. L. rohusta Stimpson, first described from Australia, reported from 

 the Galapagos Islands by Augener (1933, p. 61). 



5. L. tortugae Treadwell ( 1921 , pp. 85-86, figs. 298-304) from Florida. 



6. L. trimera Ehlers (1901, pp. 134-136, pi. 16, figs. 17-23) from 

 Juan Fernandez. 



L. sulcata Treadwell (1928, p. 200; 1921, pp. 89-90) from the 

 West Indian region has been referred to L. collaris (Fauvel, 1919, p. 

 477). Likewise, L. trimera Ehlers has been considered doubtfully distinct 

 (Monro, 1933, p. 69). All of them are very closely related to one an- 

 other; separation is difficult. L. collaris has been distinguished from L. 

 ninetta in that the shape of the eyes is reniform in the first, oval in the 

 second (Fauvel, 1932, p. 143). Only one species, L. ninetta, has been re- 

 covered in the collections.

 88-89; 1933, pp. 70-71. 



Collections.— A 15-39 (6) ; A 20-39 (1) ; A 32-39 (1). 



Distribution. — Cosmopolitan; widely reported from the West Indian 

 region and the Atlantic Panama. 



Genus NEMATONEREIS Schmarda 

 Type N. unicornis Schmarda 



Ne?natonereis is characterized in having a single prostomial antenna; 

 the prostomium is rounded in front; peristomial cirri and branchiae are 

 absent; setae include composite and subacicular hooks, pectinate and 

 simple limbate setae. 



Three species have been recorded from the Western Hemisphere. 



1. N. hebes Verrill (1900, p. 647) from Bermuda. (This should prob- 

 ably have read Fort Macon, North Carolina, as I have been able to 

 verify by examining the type; it is perhaps referable to A^. unicornis 

 Schmarda.) 



2. N. schmardae Mcintosh (1885, p. 262) off Brazil, in 350 fms. 



3. N. unicornis Schmarda (1861, p. 119) cosmopolitan.
