THE WRASSE FAMILY. 233 



is pigmented with greenish and yellow, both of which colours 

 also occur somewhat plentifully on the trunk'. 



Jago's Goldsinny. (Ctenolabrus rupestris, L.) 



Fries and Smitt^ observe that some females with running 

 roe are only 80 mm. in length, and that the spawning-period 

 extends from April to July. 



Mr Holt obtained an egg which he identified with consider- 

 able certainty about the middle of June in Inver Bay on the 

 west coast of Ireland. Its diameter was "835 mm. The capsule 

 was thin, and the yolk translucent and homogeneous. Black 

 pigment appears in the embryo, when the free caudal region is 

 noticeable, along the sides of the body and over the brain. The 

 larva measures 28 mm. and is distinguished by an elliptical 

 yolk, a pre-anal marginal fin, the vent in front of the middle, a 

 double dorsal line of black chromatophores along the anterior 

 two-thirds of the body. The notochord is unicolumnar in front, 

 at the middle third it is two-celled, and posteriorly it is 

 irregularly unicolumnar. 



Specimens four inches long are met with in July off the 

 Channel Islands, along with others about six inches. 



The Rainbow Wrasse. (Coris Julis, L.) 



Of the other representatives of this family Raffaele mentions 

 that the eggs of what he deems the Rainbow Wrasse are included 

 in a series ranging from 060 to 070 mm., with an oil-globule of 

 considerable size, viz. 016 to 018. They were procured in 

 spring and summer. The development of the egg is rapid, viz. 

 in one or two days. The larva is characterised by scattered 

 black pigment along the dorsum, an elongated yolk having the 

 oil-globule at the tip, somewhat like the red mullet, and a pre- 

 anal fin, the vent being about the middle of the body. After 

 absorption of the yolk the post-larval fish shows minute serra- 

 tions of part of the marginal fin dorsally and ventrally in front
