REPORT OX A COLLECTION OF COPEPODA MADE IN 

 HONDURAS BY F. J. DYER. 



By C. DwiGHT Marsh, 



Of the United States Department of Agriculture. 



Til is collection was contained in a series of bottles numbered from 

 1 to (59, and the material was collected at various times between No- 

 vember 28, 1915, and September 29, 1916. Every month was repre- 

 sented during that period except August. The numbers of Copepoda 

 were very small, and so many of the individuals were immature that 

 specific determination in many cases was impossible. All of the collec- 

 tions were made at La Ceiba. 



Following is a list of the species found. 



Diaptomus Tnarshi Juday. 



Cyclops leucharti Claus. 



Cyclops alhidus Jurine. 



Cyclops serrulatus Fischer. 



Cyclops prasinus Fischer. 



Cyclops ceibaensis, new species. 



Cyclops panamensis Marsh. 



Cyclops varicans Sars, determination doubtful. 



G antfiocaraptus^ species probably staphylijius. 



DIAPTOMUS MARSHI Juday.

803-805. figs. 1 and 2. 

 Diaptomus colombiensis Thi6baijd, 1914, pp. 161-163, figs. 1-5. 

 Diaptomus marshi Peabse, 1915, p. 540. 



This species was discovered by Mr. Chancey Juday in Guatemala. 

 Although it was first described by Mr. Juday in a paper presented to 

 the Wisconsin Academy, and it was understood that Marsh's descrip- 

 tion of the Panama specimens should appear after the publication by 

 Juday, by reason of an unexpected delay in the publication of the 

 Transactions of the Wisconsin Academy, Marsh's paper unfortu- 

 nately appeared in print before Juday 's. Juday found the species 

 near Puerto Barrios and Los Amates in Guatemala. Marsh found it 

 in two localities in the Canal Zone.
