quotes Dall's description of " Cyamus suffasus, n. sp." from " Proc. Cal. Acad. Sci., Dec. 

 18th, 1872." In the description of the Bowhead or Great Polar Whale (Balaena mysticetus, 

 Linn.), it is remarked, p. 57, that " the Arctic Bowhead is comparatively free from parasitic 

 crustaceans, as well as barnacles. Occasionally, however, a species of Cyamus is present 

 about the head or fins," and a footnote quotes Dall's description of " Cyamus mysticeti, 

 n. sp.," including by an obvious misprint " Length 33 inches ; breadth (of body) 16 inches." 

 The species of Cyamus are also referred to in Dall's Appendix, at pp. 301, 302, 305, on the 

 latter page Cyamus tentator, Dall, and Cyamus gracilis, Dall, being mentioned as parasites 

 of Balaena sieboldii. 



In describing the gambols of the Sperm Whale (Physeter macrocephalus, Linn.), at p. 77, 

 Scammon says, " These singular antics of the Sperm Whale are said to be performed in 

 order to rid itself of a troublesome parasite, known among the whale-fishers by the name of 

 'Suckfish'; but the animal is seldom infested with the parasitic Crustacea, which are 

 indigenous to the rorquals and Right Whales." 



On this point and on the species of Cyami here mentioned, compare Note on Liitken, 1887.

Under Arthropoda, at p. 57, Dr. Allman says, " Among the invertebrate life which abounds in 

 Arctic seas, and which from the concurrent testimony of Arctic voyagers constitute a char- 

 acteristic feature of their fauna, will be found the Amphipodous Crustacea. These are 

 small active animals, most familiarly known to us by the ' sand hoppers ' of our own shores. 

 In Arctic regions they are often attracted in countless multitudes by fragments of offal 

 thrown into the sea. To such an extent do they abound there that the carcass of a seal has 

 been in a few hours reduced by them to the condition of a clean skeleton. They frequent 

 various depths from the surface downwards, and may be all well preserved in spirit."

In the " Catalogo de los crustaceos marinos observados en las costas de las islas Baleares," at 

 page 67 the " Hedrioftalmos " comprise two Amphipods, " Orchestia Leach. 0. Montagui 

 And. [Aud.]. Pugu en Mallorca !," and " Gammarus Fabr. G. locusta Fabr. Mallorca."
