166 Prof. M‘Intosh’s Notes from the 
Coast of N. America by Mrs. Pixell-Goodrich* (1912) 
eighteen species are recorded, more than half of which are 
Spirorbids. 
The same authoress (1913) describes six in her report on 
the Serpulids of the Scottish Antarctic Expedition, three 
being Spirorbids and three other genera having one each. 
Mrs. Pixell-Goodrich (1913) enters no less than twenty- 
five species secured by Prof. Stanley Gardiner in the 
‘“‘ Perey Sladen Expedition” to the prolific waters of the 
Indian Ocean. About half of these are under two genera, 
viz. Hydroides (five) and Spirobranchus (eight), two of the 
other genera having two species and Spirorbis three. 
Twenty-nine species appear from the wide area included 
in the ‘ Campagnes Scientifiques ’ of the Prince of Monaco 
by the experienced hand of Prof. Fauvel f (1914). Seven 
of these are Spirorbids. 
In Canon Norman’s Norwegian dredgings three species 
were obtained, viz. Hydroides norveyica, Serpula vermicularis, 
and Ditrypa arietina. The same forms, with the addition 
of Placostegus tridentatus at 305 fathoms, were procured by 
the ‘Knight KErrant.? In the ‘Porcupine’ Expedition of 
1869 Protula protensa, Filograna implexa, Hydroides nor- 
vegica, and Ditrypa arietina were dredged. The list was 
slightly extended in the ‘ Porcupine’ Expedition of 1870 ; 
for, in addition to Filograna implexa, Hydroides. norvegica, 
Serpula vermicularis, Placostegus tridentatus, and Ditrypa 
arietina, a variety of Placostegus t,if not a new species, was 
obtained off Cape de Gatte in 45 fathoms, and Pomatoceros 
triqueter from Ras el Amush. The great numbers of 
Ditrypa trom Bono Bay, and their comparatively small 
size, were noteworthy. 
The paucity of Serpulids in local faunas is noteworthy. 
Thus, in the ‘ Catalogue of the Marine Invertebrates and 
Fishes of St. Andrews’ (1875) seven occur, two being 
Spirorbids, the others distributed over various genera. 
The same number is given by Marion and Bobretzky § 
(1875) at Marseilles, two belonging to the genus Apomatus, 
the others singly to different genera. Leslie and Herdman || 
(1881), in their “ Invertebrate Fauna of the Firth of Forth,” 
enumerate three Serpulids, two of which are Spirorbids.
