The material on the whole is very well preserved, and no difficulty, on the ground 

 of preservation, has lieen experienced in making out microscopic details liy means of 

 sections or otherwise. On the other hand, the number of specimens in some cases is 

 so small that it was thought undesiralile to dissect them to any great extent, and the 

 accounts given of their structure must be regarded as subject to modification at some 

 future time, when more abundant material may be available. 



It is a matter for regret that almost no rcord appears to have been kept of the 

 colours and markings of the various species during life. The specimens, by the time 

 that thev were handed over to me for study, were all, with a very few exceptions 

 wliicli will be mentioned in their appropriate places, deprived of all traces of their 

 natural colours bv the .spirit in which they had lieen stored. 



Transverse sections taken by hand were employed as a means of assigning many 

 of the specimens to their position. This method was found extremely valuable for 

 rapidly sorting individuals which were so contracted, or of such nondescript external 

 appearance, as to be inseparable by mere inspection. The sections were lightly stained 

 with Paracarmine or ricrocarmine, and rapidly differentiated, dehydrated, cleared 

 (preferablv in Xylol) and mounted in Balsam. In the cases where serial .sections were 

 made, the best results were obtained by staining on the slide with Hajmalum. or 

 with Delafield's Hsematoxylin followed by Eo.sin. 



Creosote was found useful in clearing some preparations, such as the pmboscis o]
