Collections.— 11^-3^, 903-38, Mission Bay. 11 specimens. 



The prostomium consists of 14 annuli or more. Branchial lobes are 

 first present from the twentieth parapodium (Mission Bay) to the 

 twenty-fifth segment (903-38). Ehlers (1868, p. 664) noted them from 

 the sixteenth parapodium in specimens from Naples, and Monro (1930, 

 p. 117) reported them from the twelfth segment in collections off south- 

 west Africa. Branchiae are continued posteriorly nearly to the end, but 

 are absent from a few of the posteriormost segments. 



These specimens differ from G. alba most notably in having longer 

 branchial lobes ; the accessory jaw piece is longer, the base more divergent. 

 The proboscidial papillae are of two kinds, a much more numerous chit- 

 inous papilla, and a few, scattered tiny, rounded papillae. 



Moore (1911, p. 301) separated G. macrobranchia from typical G. 

 alba Miiller because the branchiae of the former are notably larger. This 

 is the case in G. convoluta Keferstein. The proboscidial papillae described 

 by Moore seem to agree with those for G. convoluta. 



Distribution. — North and south Atlantic; Mediterranean; southern 

 California. Littoral.
