BIOLOGICAL SURVEY OF WOODS HOLE AND VICINITY. 93 
The following is a list of the Foraminifera dredged by the Survey. The asterisk 
denotes species which were recorded from 10 or more stations: 
Astrorhiza limicola. Miliolina bicornis. 
Reophax dentaliniformis. Verneuilina polystropha. 
Haplophragmium canariense. *Polymorphina lactea (chart 5). 
Webbina hemispherica. Polymorphina concava. 
Spiroculina limbata. Polymorphina rotundata. 
*Biloculina ringens (chart 1). *Discorbina rosacea (chart 6). 
Biloculina tubulosa. Truncatulina lobatula. 
*Miliolina seminulum (chart 2), | *Pulvinulina lateralis (chart 7). 
*Miliolina oblonga (chart 3). *Rotalia beccarii (chart 8). 
*Miliolina circularis (chart 4). *Polystomella striatopunctata (chart 9). 
Miliolina boueana. Polystomella crispa. 
Miliolina venusta. 
2. PORIFERA. 
The treatment of the sponges constitutes decidedly the weakest spot in our report. 
In addition to the naturally great difficulties presented to the systematist by these 
animals is the fact that the group has been very largely neglected by local zoologists. 
Since the work of Verrill in the early seventies, in which a considerable proportion of 
the forms recorded were not specifically determined, no attempt has been made to list 
or describe the sponges of the shallower waters of the New England coast. Verrill’s 
later studies were devoted to species taken at considerable depths and belonging to a 
fauna quite distinct from that under consideration. Lambe,® it is true, has given much 
attention to the Canadian sponges, some of which are identical with species included 
in the present work, and H. V. Wilson® has reported upon the Porto Rico forms, 
none of which, however, are known to occur in the Woods Hole region. The paucity 
of our data relating to the shallow-water species constitutes a conspicuous gap in our 
knowledge of the local fauna. 
In view of this condition of affairs, Dr. J. A. Cushman, of the museum of the Boston 
Society of Natural History, undertook during the summer of 1905 and during the fol- 
lowing winter to identify the sponges collected in the course of the Survey dredging. 
Twelve species were specifically determined by him with more or less certainty, four of 
these being forms which had been overlooked or left unidentified by Verrill at the time 
of the writing of the ““Report upon the Invertebrate Animals of Vineyard Sound.” 
Certain other species were provisionally assigned to genera, and an even greater number 
remained undetermined. It was unfortunately impossible for Dr. Cushman to continue 
this work after 1905, and thus the results here presented are fragmentary and perhaps 
not wholly consistent. 
In all, 14 determined species of sponges are comprised in our annotated list, the 
identity of which is not certain in all cases. We have also included, on the authority of 
Verrill and of Cushman, a number of unidentified forms, to which generic names have 
been provisionally assigned. 
The Canadian list of Whiteaves comprises 36(+ 2°?) species of Porifera (identified 
in the main by Lambe), six of which are common to our Woods Hole list. At Plymouth 
only 18 sponges have been catalogued, of which four or five are common to our own
