By H. H. bloomer. 



Journ. Malac, 1901, Vol. viii, page 37, line i, for "its widest part," 

 read "its deepest part." 



Line 24, for "siphonal chambers are short," read "siphonal chambers 

 are very short." 



Line 25, "and at the distal end of each chamber are two flaps forming 

 the valve." 'J'his applies more particularly to *S. vagina (marginatus) as these 

 valves are not at all pronounced in E. ensis and E. ailvpia. 



Page 38, line 36, for " a circular growth " read " an elliptical growth." 



Line 39, for "the circular muscular arrangement" read "the elliptical 

 muscular arrangement." 



Page 40, line 41, "and pass underneath instead of over the longitudinal 

 muscles " — that is, viewed from the pedal cavity ; actually, they pass between 

 the longitudinal muscles and the pedal integument. 



Page 98, paragraphs 2 and 3, for " viscero-parietal ganglion " read 

 " viscero-parietal ganglia " in all three cases. 



Journ. Malac, 1902, Vol. IX, page 134, line 25, "and pass underneath 

 instead of over the longtitudinal muscles." This means, as viewed from the 

 pedal cavity, correcting speaking, they pass between the longitudinal muscles 

 and the pedal integument. 



Page 135, line 4, for "distal " read " proximal." 



Journ. Malac, 1903, Vol. x, page 31, line 10, for " and proceed posteri- 

 orly " read " and on the dorsal surface proceed posteriorly." 



Line 24, for "tentacular" read " crenulated." 



Page 32, line 6, for " pass round the anterior end," read " pass from 

 the dorsal surface around the anterior end." 



Line 24. after .V. uiarg hiatus, add, " that is, as viewed from the pedal 

 cavity, but correctly described should be, between the longitudinal muscles 

 and the pedal integument." 



Line 25, for " retractor pedis posterior muscles are longer," read 

 ' retractor pedis posterior muscle is longer." 



Page 33, line 26, for " wide " read " dee[)" and for " width " read 

 " depth." 



Page 34, line 27, for " width " read "depth." 



Page 34, lines 28 to 31. It was after writing this sentence that I saw 

 the article l)y Prof H. Von Ihering (The Musculus cruciformis of the 

 Order Tellinacea *), .md this muscle is evidently a modilied form oi his 

 musculus cruciformis.
