No. 8.] WHITEAVES — W. COAST INVERTEBRATA. 465 



The following is a list of the species recognized so far. 



Hydrozoa. 

 Littoral species, collected near Victoria by Mr. R. Middleton. 



AgJaiophenia struthionides. 

 Plumularia setacea. 



Scrtidaria anguina, Trask, var. robusta. 

 Sertularella Greenii. 



" turgida, Trask. 



OleUa. (Sp. Uudt.) 

 Tubularia. (Sp. Undt.) 



Alcyonaria. 



VerriUia Blakci, Steams. Five fine living specimens of this 

 gigantic and remarkable Pennatulid were obtained by Mr. 

 Richardson from Burrard's Inlet, in between 10 and 20 

 fathoms, in 1874. These have since been received in a 

 beautifully perfect state of preservation, as alcoholic prepar- 

 ations, but Mr. Stearns' description of the species (on pages 

 147 to 149 of the fifth volume of the " Proceedings of the 

 Caiifornian Academy of Sciences ") is so exhaustive and 

 accurate, that they give very little additional information on 

 the subject. The largest specimen collected by Mr. Rich- 

 ardson is seven feet and eight inches long, the length of the 

 naked basal portion being just two feet. The polyps, which 

 are sessile, are arranged in crowded, subimbricating, obliquely 

 transverse rows, "in two unilateral longitudinal series." 



i Mr. F. B. Caulfield has carefully counted the exact num- 

 ber of polyps in one of the longitudinal series in this speci- 

 men and finds it to be 3802 - r the number of transverse rows 

 in the same series, including the shortest ones, being 369. 

 On the supposition that there is an equal number in both 

 series, the total number of polyps in this individual would 

 be 7604 1 In a specimen 66 inches long, described by Mr. 

 Stearns, it has been estimated that there would be about 

 5000. 



It would appear that this or a very similar species is 

 found also off the coast of Alaska, for in a letter by the 

 anonymous author of the quaint narrative of the voyages of 

 the King George and Queen Charlotte, published under the
