REVISION OF THE FISH FAMILY LIPARIDAE 61 



L. atlaniicus may be the only described species of Liparis on our 

 Atlantic coast. (See L. tunicatus.) Putman and later Garman (for 

 other records see Kendall 1908 and Tracy 1909), record L. liparis 

 from this region. Specimen No. 12958; Garman 1892 (pi. 7, figs. 1 , 2, 

 3, 4), appears to be distinct from L. liparis. The number of coeca is 

 greater and the disk is larger, both agreeing with L. atlaniicus. The 

 specimen is in such condition that the other characters can not be 

 ascertained though the anal appears to be as figured, and the colora- 

 tion striped. Some immature specimens from Block Island and Noank 

 found in pectens seem to differ from L. atlaniicus in the increased 

 connection between the dorsal and the caudal. They probably, with 

 No. 12958, represent some other species, possibly an undescribed one. 

 These specimens have probably been separated from L. atlaniicus 

 and placed with L. liparis because of the absent or obscure dorsal 

 notch and the extent of the connection between dorsal and caudal fin. 



Specimens of L. atlaniicus one-half inch in length have been taken 

 on the 31st of July. Putman (1873, 339), records that the spawning 

 season is in March. 



UPARIS MONTAGUI (Donovan) 



Cyclopierus montagui Donovan, 1805, pi. 68. 

 Liparis montagui Gunther, 1861, p. 161. 



Distribution. — Coasts of northern Europe, recorded from the north 

 of France northward. No specimens examined. 



Relationship. — A discussion of the possible differences between L. 

 montagui and L. atlaniicus are given in the description of the latter. 



UPAKIS RUTTERI (Gilbert and Snyder) 



Neoliparis ruiteri Gilbert and Snyder, 1898, in Jordon and Evermann, 1898, p. 

 2108. — Evermann and Goldsborough, 1907, p. 331, fig. 99. 



Types 3, No. 5701, S. U. Z. M., Uyak Bay, Kodiak Island, Alaska; 

 Rutter, 1903. Length 65 mm. 



Distribution. — Known from the southeast coast of Alaska and the 

 Aleutian Islands; tide pools to 16 fathoms. Twenty-four specimens 

 examined. 



Relationsliip . — L. ruiteri closely resembles L. atlaniicus. The only 

 differences between the two species are found in the coloration and the 

 number of pectoral rays. L. ruiteri appears to have a slightly larger 

 disk than L. atlaniicus and never has prickles. L. ruiteri can be 

 distinguished from all the Pacific species by the large disk combined 

 with the coloration. 



Synopsis. — Dorsal 31-32; anal 23-26; pectoral 30-33; pyloric coeca 

 23-31 . Disk 1 .4-1 .7 in head. Gill slit above the pectoral. Spinous 

 dorsal usually distinct but sometimes hardly evident; the spines some- 

 times elevated. Caudal typically connected for less than one-fifth 

 its length to the dorsal. Disk large, less than 2 in head. Prickles
