end is fnrnislied with a small pentangular opening of a red 

 colour." 



Fleming, 1828. — ITolothuria Montagui. " Tentacnla eight, 

 with two small contiguous subsidiary ones. Mouth simple." 



(Here reference to Montagu.) 



" The body is cylindric, white, covered with a mottled cuticle ; 

 towards tiie head the wliole becomes purplish-brown ; margin 

 of the mouth white; while alive the two small subsidiary 

 tentacula are alternately in motion, covering the mouth ; 

 vent pentangular^ red. The divisions of the tentacula are 

 not so numerous as in the preceding species." 



Thus the whole of the description of the species is actually 

 a quotation from Montagu down to the word ''red," and 

 then, as though Fleming intended to signify this fact, the 

 first full stop occurs after ^' red " ; and a capital letter com- 

 mences the sentence '^ The divisions of the tentacula are not 

 so numerous as in the preceding species. ^^ He gives a locality 

 '' Firth of Forth, Mr. Neil " ; but it may be questioned 

 whether Fleming ever himself saw a specimen which he 

 would refer to Montagu's Holothurian, for the sentence 

 respecting the tentacula might w-ell be written from a com- 

 parison of Montagu's figure with the tentacles of the species 

 which he (Fleming) called Holotliuria peniactes, Mr. Pace 

 writes of '' Montagu's excellent description " ; but " the 

 description of C. Montagui is-, based upon specimens of another 

 species collected in the Firth of Forth." It is unnecessary 

 to write more. — Cucumaria Montagui (Fleming') stet. Cucu-

In my former paper I carefully described the spicula of 

 Cucumaria Montagui. That description need not be repeated ; 

 but I Lave here given illustrations of the spicula, both lower 

 and upper^ of the dermis together with those of the feet and of 

 the tentacles. Fig. la, b, and c (PL XL) are normal and 

 characteristic examples of the spicula of the lower layer. 



Specimens B and C. 

 What are the specimens which in my paper I called B and 

 C ? Are they the young of C. Montagui, or are they a distinct 

 species as Mr. Pace considers them to be? Pi. XI. fig. 5 

 represents a specimen, slightly enlarged, which was sent to 

 me from Plymouth by Mr. Pace himself. Fig. 6 represents 

 the body-spicula and fig. 7 the spicula of the feet. Of these 

 figures, fig. 6 a, b, c represent the spicula with six openings 

 which distinguish this condition, and are not found, so far as 

 1 have observed, in full-grown C. Montagui. g, //, ?', k are
