Spirorbis tuboeformis — Continued. 
Phalarope stations*: 8 (several tubes), 17 
(tubes), 18 (many), 56 ? (abundant), 57 ? 
(abundant), 58 ?, 63 (several), 66 (several 
tubes), 79 (common), 87 (on red algae), 100 ?, 
X12 (common). 
Supplementary records ® during the summer and 
fall of 1908, in the vicinity of the following 
former stations: 7325 (abundant on Phyllo- 
phora), 7545 (1 on Phyllophora), 7393 (1 on 
Polysiphonia elongata), 7632 (few on Phyllo- 
phora), 7670 (on Phyllophora), 7692, (abundant 
on stones), 7722 (few on Phyllophora), 7726 
(abundant on Phyllophora), 7738 (1), 2 (abun- 
dant on Phyllophora), 16 (abundant on Phyllo- 
phora, a few on Chondrus crispus and on shell 
of Ensis directus), 107 (few on Phyllophora) , 
117 (abundant on Phyllophora, a few on 
Sargassum filipendula) , 161 (fairly numerous 
on Phyllophora ). 
To this species probably also belong the majority 
of specimens referred to under the head 
“ Spirorbis sp . sp . ” 
Spirorbis, sp. sp. (probably for the most part 
S', tuboeformis, though perhaps comprising a 
certain proportion of S. spirillum and possibly 
also of S. spirorbis). 
During the first summer’s dredging, and probably 
to some extent later, the various species of 
Spirorbis were confused by the collectors 
in the field. For this reason, all records 
made during that period, unless known to 
be based upon Dr. Moore’s identifications, 
have been thrown together under this head. 
The unequivocal records, which, of course, 
form very incomplete lists, have been in- 
cluded under their respective species. Owing 
to the unsatisfactory condition of the data 
for this genus, numerous supplementary 
dredgings were made during the summer and 
fall of 1908, the results of which have been 
incorporated in the accounts given above.

Spirorbis — Continued. 
Phalarope stations: 1 (few), 2 (several tubes), 
3 (several tubes), 16 (many), 30 (several), 32 
(plentiful), 33 (tubes on algae), 65 (many), 67 
(very abundant), 83 (2 tubes on red algae), 86. 
Spirorbis spirillum (Linnaeus). 
Verrill and Smith, 1873, P- 622, 498, etc. ( Spiror- 
bis lucidus and N. porrectal). 
Vineyard Sound, near mouth; off Gay Head, 
in 10 fathoms; off Buzzards Bay, in 25 fathoms. 
— Verrill. We have several unequivocal 
records for this species at Survey dredging 
stations of the regular series in the western 
part of Vineyard Sound; one in Buzzards 
Bay, west of Woods Hole. A special search 
during the summer and fall of 1908 revealed 
its occurrence at six points in Vineyard Sound 
beyond Robinsons Hole ; none in more eastern 
parts of the Sound, and none in Buzzards Bay. 
The tubes were attached to Phyllophora and 
Chondrus crispus, once to a bit of eelgrass, 
and were in some cases associated with Spiror- 
bis tuboeformis. A species which was probably 
S. spirillum was likewise found in abundance 
on some eelgrass (drifting ?) found near the 
landing of the Bureau of Fisheries residence 
in Woods Hole Harbor. — Sumner. Some 
specimens in the museum bear the label “ Crab 
Ledge.” 
Fish Hawk station 7611 (many)*. 
Phalarope and Blue Wing stations*: 20 (many 
tubes), 24 (many on algae), 23 (many), 36 
(common), 44 (several tubes), 43 (1), 49 
(several tubes). 
Supplementary records,® during the summer of 
1908, in the vicinity of the following former 
stations: 7599, 7695, 7722, 7726, 7729, 58. 
Spirorbis quadrangularis Stimpson. 
Crab Ledge, at Fish Hawk station 7605*; 17 
fathoms, gravel; tubes attached to shells. 
Abundant specimens of a Spirorbis, in part, 
perhaps, of this species, are recorded for Fish 
Hawk stations 7604, 7607, 7608, and 7609 
(all at Crab Ledge). Samples of these were 
unfortunately not preserved, since their 
identity with the others was taken for granted 
at the time by the collectors. 
Spirorbis fewkesii Bush and 5 . stimpsoni Verrill. 
Included by Dr. Moore (MS.) as “Woods Hole 
species,” but no more definite data are avail- 
able at present. 
“These specimens were identified by F. B. Sumner.
