 I Fodgangenes indre Deel er der 3 

 ydre Fodpapiller i livert Sfet. 



"Hos det noeststorste (C) (R=84 

 mm, r=31mm) bestaa^r 'Borgen'

 * Taarne ' normalt'^ af to for liver af

 og forbnndne indbyi'des og med liine 

 ved et stœrkt Net af Rygtavler, som 

 omslutte sferskilte Porefelter. Deres 

 Stilling nfermer sig snart til det lod- 

 rette, snart til det vandi-ette. At de 

 sraaae Porefelter, hvoraf de ovenfor 

 (ved A) beskrevne 4 större sammen- 

 sfettes, lios dette og det folgende 

 Exerùplar i det liele vise sig mere 

 sondrede, er maaskee tildeels en Folge 

 af Indtön-ingeu, men künde maaskee 

 ogsaa tildeels vsere en Folge af, at 

 Hudskelettet med Alderen udvikledes 

 noget stserkere, og at Grsendsen möl- 

 lern de enkelte Porefelter derved blev 

 noget tydeligere. — Selv i Amiens in- 

 dre Deel findes der hos dette Ex- 

 emplar kun 2 ydre Fodpapiller i 

 hver Gruppe.

 et Forliold mellem Stjernens Radier

the former. Apadicellaria with long 

 jaws is placed between each set. 



"The next smallest Example (B) 

 (R = 70mm, r = 26) deviates essen- 

 tially from the smaller only by a more 

 complicated structm-e of the * castle,' 

 which may better be described under 

 the following example. In the inner 

 part of the ambulacral fmTow there 

 are throe outer foot papillEe in each 

 set. 



"In the next largest (C) (R = 84 

 mm, r = 31mm) the 'castle' consists, 

 in addition to the 5 towers enumera- 

 ted under A, normally^^ of two for 

 each of them, situated more inferi- 

 orly, immediately over the beginning 

 of the back of the arms and joined 

 with one another and withthe ' towers ' 

 by a stout net of dorsal j)lat3S, which 

 enclose the separated poro-aroas. 

 Their attitude is sometimes more 

 nearl}" vertical, sometimes more nearly 

 horizontal. That the small pore- 

 areas, of which the above (in A) 

 described 4 larger ones are composed, 

 present themselves on the whole better 

 separated in this and the following 

 example, is perhaps partly a result 

 of dessication, but may perhaps also 

 be partly a result of the fact that 

 the dermal skeleton is developed more 

 strongly with ago, and that the boun- 

 dary between the several pore-areas 

 became thereby somewhat more dis- 

 tinct. — Even in the inner part of the 

 arm there are in this example only 

 2 outer foot papillae in each group. 



" The largest example (D) has the 

 ratio between the radii of the st.ir = 

 nearly 1:3 (r = 35, R = 100 mm) ; the

 (they have not yet appeared) from one of the
