remainder over to tin- mess, and there are many witnesses to testify to the superior character of 

 the deep water Prawns as an article of food. 



The lohstermeii of Itiddet'ord Pool, Maine, who set their pots ill the winter from four to si x 

 miles from shore, occasionally capture these Prawns, and here may be a suggestion as to the' 

 style of apparatus which mijjht IK' tried advantageously for their capture. The openings would, 

 of course, need to he of much smaller si/e than those of an ordinary lobster-pot. A light beam 

 trawl of large six.e might, however, answer still better. 



THE CALIFORNIA PRAWN PANDALUS DAN-*:, Stimpson. 



According to W. N. Lockington, this is a moderately large species of Prawn, which is now 

 commonly brought to the San Francisco market, and is caught in the open ocean between the 

 Farallone Islands and Point Reyes. The length of the body in the adults, including the rostrum, 

 is aliout live inches, while the average length of the carapax, excluding the rostrum, is about one 

 and a quarter inches. Fresh specimens are finely marked with transverse zigzag lines of white, 

 separated by bands of red. 



Pandulun Dana: has been recorded from the Queen Charlotte Islands and Puget Sound, north 

 of which it is not known; its southern limit is possibly Point Conception, California, the most 

 pronounced point of division between the northern and southern marine faunae of California, 

 though this fact has not been positively determined. This Prawn has been much more abundant 

 in the Ban Francisco markets during the past two years than formerly, and the reason assigned is 

 that the tishermen, driven out of San Francisco Bay by the constantly diminishing supply of fish 

 there, have been forced to resort to the open sea between the Farallone Islands and Point Reyes, 

 where the Prawns live in large numbers. It has been noticed with spawn in November, Decem- 

 ber, and January. A second species of Prawn is occasionally brought to the San Francisco 

 market, along with P. Dance, being obtained in the same places. It is of smaller size than P. 

 Dante and of a uniform light pink color when fresh; it also differs from the latter in the size and 

 shape of the rostrum, appendages, etc., and in the number of the rostral spines. 



In 1879, several examples of a large species of Prawn, apparently identical with Penceus 

 brasiliensi*, of Brazil and the Southern United States, were brought to the San Francisco 

 markets; in 1880 none were observed. This species is also recorded from the west coast of 

 Nicaragua. Adult specimens examined at San Francisco measured seven inches in total length, 

 including the rostrum. Compared with specimens from the Bio Grande, Brazil, no points of 

 difference as regards form or proportion of parts were detected. 



THE SOUTHERN SHRIMPS AND PRAWNS fanyjEus SETIFERUS, M.-Edwards; PEN^EUS BRASIL-

These are the large Shrimps or Prawns which occnr in such immense numbers on the coasts 

 of the Southern States, and are taken to supply the markets at Charleston, South Carolina; 

 Savannah, Georgia; New Orleans, Louisiana: New York, and elsewhere. The two species are 

 often found associated together, but Penteus seti/ertis is the more abundant, nnd is, therefore, more 

 commonly seen in the markets. According to Prof. Lewis R. Gibbes, these species may*be dis- 

 tinguished apart by the following characters: 



"The common Shrimp (P. netiferus) has a groove on each side of the large spine that springs 

 from the fore and upper part of the shell or carapax; these run backward and terminate about 

 the middle of the length of the shell. In the same tray in the market will frequently be found 

 other individuals, far less numerous, in which these grooves run the whole length of the shell, 

 terminating just in front of the hinder edge or border of the shell, at the first joint. This form I 

 have referred to the P. brasiliewi* of Lat reille.
