tudy material. A number of taxa from these collections have been 
assigned and redescribed in the light of taxonomic work carried 
ut on the County Fermanagh fauna. 
Specimens have been deposited in a number of museums. The 
gest collection is lodged in the Natural History Museum, London 
refix BMNH PD). A voucher collection which includes some 
aratype material has been lodged in the Geological Museum, 
trinity College Dublin (prefix TCD. ). In addition some paratypes of 
| number of fenestrates (see Wyse Jackson 1988) have been depos- 
_ted in the National Museum of Ireland (prefix NMING:F) and the 
Jister Museum (prefix BELUM K). 
| Morphometric measurements for every taxon were taken on at 
past 12 specimens, if available, and up to ten measurements were 
nade on each parameter on each specimen, using a Leitz binocular 
-ficroscope fitted with a linear graticule at magnifications of be-

tween x40 and x100.The mean, standard deviation, and intracolonial 
and intercolonial coefficients of variation were computed and are 
tabulated within the description of each taxon. Abbreviations used in 
these tables are: CV = Coefficient of Variation; CV w = Intra (within) 
Colonial Variation; CVb = Inter (between) Colonial Variation; NM = 
Number of measurements; Mn = Minimum value recorded; Mx = 
Maximum value recorded; x = Mean value; N = Number of speci- 
mens measured; explanations for other abbreviations used are given 
in Figs 3, 18, 42, 59 and 84. 
The measurement scheme for cryptostomes is modified from 
Newton (1971) (Figs 3, 18); for fenestrates from Tavener-Smith 
(1973) (Fig. 42); for trepostomes from Boardman (1960) and Cuffey 
(1967) (Fig. 59); and for cystoporates from Warner & Cuffey (1973) 
(Fig. 84).
