or 1 -]- 7 rings ; there are 14 or 15 body rings, and from 37 to 41 

 caudal rings (the ring containing the vent counted as a caudal 

 ring) ; the caudal pouch covers from 20 to 24 rings. 



This species differs from Syugnathus leptorhynchus in having: 

 the angles of the body sharper, the head shorter, the snout 

 shorter, and with a more prominent median keel, the caudal 

 pouch longer, and the body rings fewer. In the latter species the 

 head is contained from Bi/o to 8i/> times in the length without 

 caudal ; the body rings number from 16 to 19 ; and the brood- 

 pouch covers 19 to 20 rings. 



It is known southward to Panama (Gilbert and Starks, 1904, 

 p. 57) ; taken in Magdalena Bay (Gilbert MS. notes) and the 

 Gulf of California.

 {Sip]tusto7na barbarce, Jordan and Evermann, 1896, I, p. 765). 

 Only the type from Santa Barbara known. 



55. Syngnathus arctus (Jenkins and Evermann). 



SHORT-NOSED PIPEFISH. 



{Siphostorna arcium, Jordan and Evermann, 1896, I, p. 771.) 

 Three specimens seined in San Diego Bay, and two taken in 

 tide pools at La Jolla. They are the first that have been seen 

 since the type was taken in the Gulf of California in 1888. The 

 species has been erroneously recorded from Mazatlan (Jordan, 

 1895, p. 416). 



Our specimens agree in all respects with the type which has 

 been kindly loaned us by the U. S. National Museum. 



The following color description was made from a male and a 

 female specimen from San Diego Bay : Color, brown ; a double 

 row of dark spots along side back to vent; one on each plate. 

 Belly ridge of female black ; ridges on each side of pouch of male 

 black. Ventral side of head anterior to a white transverse streak 

 just behind eye marked with fine irregular cross streaks of white 

 and l)rown in the female, with white dots in the male. At each 

 angle behind vent, between each plate is a white dot (this is not 

 evident in alcoholic specimens).
