358 Canon A. M. Norman on Cucumaiia Montagul. 



de Monaco, Contrib. a rfitude des Holothuries de PAtlantique 

 Nord/ 1893, p. 15, and tliere, under Cucitmaria Montagni, 

 found a reference to a paper of Prof. Jeffrey Bell which iiad 

 escaped my memory and to which no reference is made in 

 that author^s more recent publication ' Cat. Brit. Echin. in 

 B.M.' On turninjj to this paper by Bell, " On the Spicules of 

 Cucumaria Jhindninnni and calcigera and two allied Forms," 

 Journ. E. Micros. Soc. ser. 2, vol. iii. 1883, I learnt that 

 types of Montagu's Cucuraarian were in existence in the 

 British jNIuseum. 



I at once went up to the Museum, and with the kind 

 assistance of Professor Bell examined these interesting speci- 

 mens, with the following most satisfactory results. The 

 names and other remarks which I enclose in inverted commas 

 are in the handwriting of Leach, while the name annexed 

 has been written on a more recent label. 



Bottle 1. ^' Holoihuri'i Montagni, S. Devon, G. Montagu, 

 Esq., Mus. Leach.-" 0. Planci. 



This is a large specimen, about six inches, but I 

 did not measure it. It is my A, with extremely 

 numerous four-holed spicules in the lower layer, and 

 with plenty of the characteristic campanulates in the 

 upper. 

 Bottle 2. '^ rioJothuria decollata, South Devon, G. Montagu, 

 Esq., Mus. Leach .•'^ Pentacta Montagui, Gray. 



This is a much smaller sjDecimen, agreeing with my 



B in spiculation, but smooth four-holed and dumbell 



forms most frequent, only a few with six perforations. 



Bottle 3. '' Cucumaria communis. South Coast of Devon, 



Mus. Leach .'^ C. Planci. 



The spiculation of these three or four small speci- 

 mens is in entire agreement with my form B. 

 Thus striking facts confirmatory of my views come out : — 

 1st. That at each of three places where adult C. Montagni 

 have been found — South Devon [Montagu) ^VoX'^tvxo [Norman) , 

 Plymouth (Pace) — there also small specimens have been 

 found with the spiculation of my B and C. 



2nd. That in the British Islands Cucumarians with the 

 spiculation of B and C have only been found at these three 

 places. 



3rd. That no small examples are known to occur having 

 the same spiculation as the adult C. Montagni. 



I give in the list below some synonymy, but do not refer 

 to continental authors, leaving them to reconcile differences 

 now that they will have full illustrations of the spicula of 

 C. Montagui. In 1886 I sent specimens agreeing with B and
