PREFACE. 



sailors in warm and temperate seas, but of which no good figure 

 from life has been given before. 



The fifth plate shows our common Picked Dogfish to be identical 

 with the European Acanthias vulgaris. 



The sixth and seventh plates give figures of the Sepioteuthis 

 Australis, one of our large species of the ten-armed group of 

 Cuttlefishes, having a row of horny spines round the edge of 

 each of the suckers ; and having a transparent internal horny 

 "pen," popularly mistaken for an approach to the backbone of 

 the vertebrate animals by rash upholders of the "progressive 

 development " theory. 



The eighth plate gives illustrations of the Victorian species of 

 Bugula, contributed by Dr. MacGillivray to the National Museum 

 and this work. 



The ninth plate represents the character of one of the curious 

 twig-like Phasmce of the genus Acrophylla, showing the striking 

 sexual differences. 



The tenth plate figures the female of the greatest of our 

 gigantic Phasmce, the large pink-winged Phasma of the genus 

 Podacanthus, showing the colours of life for the first time. 



The succeeding Decades will illustrate as many different genera 

 as possible, and will deal first usually with species of some special 

 interest, and of which good figures do not exist, or are not easily 

 accessible.
