NO. 1 HARTMAN : POLYCHAETOUS ANNELIDS 105 



6 to 8 right, maxilla III has 6 or 7 left, none right, maxilla IV has 5 to 

 6 left, and 10 to 11 right. A black spot is present on the dorsal base of 

 parapodia. 



The original description of E. longicirrata is somewhat confused, 

 since the prostomial antennae were said to be "all very delicate smooth" 

 and the dorsal cirri large, long, and irregularly wrinkled. Treadwell 

 (1921, p. 14) corrected these statements after a re-examination of Web- 

 ster's type and showed that the antennae and dorsal cirri are actually 

 articulate. Later, Monro (1930, p. 121) redescribed E. longicirrata, 

 based on individuals from the Gulf of Guinea, differing from the origi- 

 nal, however, in that there are usually nearly 100 branchial and only 

 about 40 postbranchial segments; the acicula are said to be black and 

 the maximum number of branchial filaments only 4. It appears, there- 

 fore, that these are not the same as Webster's species. Monro also re- 

 ferred E. antillensis Ehlers (1887, p. 84) from off Florida, to E. longi- 

 cirrata. I believe, however, that Ehlers' description includes more than 

 one species because it was said, by the original author, to have "aciculae 

 nigrae vel flavae," also "branchiae a pinna 4a usque ad pinnam 40am, 

 maximae ? 5-6, c? 2-filosae." 



Through the courtesy of the U. S. National Museum, I have been 



able to examine slides of the type of E. longicirrata Webster (U.S.N.M. 



no. 4792) prepared by the original describer. These are: 



No. 54, with middle branchial segments. In these, branchial filaments 



number 13 and 14; parapodia are each provided with composite 



pectinate and limbate setae and 2 acicula; there are no subacicu- 



lar hooks. 



No. 208, with parapodia one to 4. These have each 2 or 3 acicula that 



are distally spatulate. 

 No. 209, with parapodia 5-7. Branchial filaments number 13 on a para- 

 podium; there are no subacicular hooks in these parapodia. 

 No. 210, with parapodia from middle segments. There are 6 parapodia, 



each with 2 subacicular hooks but no branchiae. 

 No. 211, with parapodia from middle branchial segments. There are 3 

 parapodia; branchiae have 9 to 11 filaments; there are no sub- 

 acicular hooks. 

 No. 212, with postbranchial segments. This slide has 5 parapodia, all 

 with branchiae that have 1 to 4 filaments; each parapodium has 

 one (or also a second embedded) subacicular hook. 

 No. 213, with posterior fifth segments. There are 5 parapodia, all lack- 

 ing branchiae ; each has 2 subacicular hooks and 2 acicula.
