BIOLOGICAL SURVEY OF WOODS HOLE AND VICINITY. 1 63 



The following is a list of the species of fishes recorded during the survey dredging. 

 The asterisk, here as elsewhere, denotes those species which were taken at 10 or more 

 stations.

 *Syngnathus fuscus (chart 199). 

 *Ammodytes americanus (chart 200). 



Poronotus triacanthus. 



Centropristes striatus. 

 *Stenotomus chrysops (chart 201). 

 *Tautogolabrus adspersus (chart 202). 



Monacanthus hispidus. 

 *Spheroides maculatus (chart 203). 

 *Myoxocephalus asneus (chart 204). 



Myoxocephalus octodecimspinosus. 



Hemitripterus americanus. 



Cyclopterus lumpus. 



Neoliparis atlanticus.

 *Pholis gunnellus (chart 206). 



Ulvaria subbifurcata. 



Zoarces anguillaris. 



Merluccius bilinearis.

Limanda ferruginea. 

 *Pseudopleuronectes americanus (chart 209). 

 *Lophopsetta maculata (chart 210). 



Lophius piscatorius. 



The 13 most common species which were taken in the dredge may be grouped as 

 follows in respect to their known geographical range : Predominantly northern, 2 ; pre- 

 dominantly southern, 5; approximately equal, 6. The ranges for these species will not 

 be stated here, since these are given in the table below, which gives the distribution 

 of all our local species. 



Leaving the consideration of these few species which were taken with the dredge 

 and passing to a consideration of the entire array of species which have been reported 

 from the vicinity of Woods Hole, we may say that our local fish fauna is overwhelmingly 

 southern in its character. In the subjoined lists the Woods Hole fishes have been 

 grouped into (1) those which are predominantly northward ranging; (2) those which are 

 predominantly southward ranging; and (3) those which have an approximately equal 

 range in both directions or regarding which the data are not sufficiently known. The 

 distributions here stated are taken in the main from Jordan and Evermann's "Fishes 

 of North and Middle America," supplemented by data published by H. M. Smith and 

 by W. C. Kendall. 



It will be seen that only 29 species, or less than 12 per cent of the entire number, 

 are grouped among the northward-ranging forms, while over 75 per cent are grouped 

 among the southward-ranging forms. The remaining 13 per cent can not well be classed 

 in either division, and they have accordingly been grouped by themselves. 



Viewing these data in another way, it will be seen that nearly half of the total 

 number of species (48 per cent) have not been recorded from any point north of Cape 

 Cod. In this connection allowance must of course be made for the possibility that the 

 frequent appearance of Cape Cod as the northern limit of distribution, according to 

 published reports, results largely from the circumstance that the fishes of Cape Cod 

 and vicinity have been more fully listed than those of almost any other point on the 

 coast. An equally diligent search of the waters to the northward will probably reveal 

 the presence of many species which have hitherto been supposed to be limited bv this 

 barrier. 



o For example, Kendall (1908) records a number of species for northern New England, which by Jordan and Evermann were 

 not listed for points to the north of Cape Cod.
