fragment 7^ mm. long, and consisting of the proboscis^ collar, 

 and part of tlie branchial region. Unfortunately-, the speci- 

 men was not of much nse for anatomical purposes. Its 

 external features (and what little it was possible to make out 

 of its internal anatomy) agree so closely with Spengel's 

 description of Glossobalanus minutus (Ptychodera 

 mi nut a) — notably in the possession of the triangular 

 " Kiemenfeld," which Spengel regards as characteristic of 

 the species — that, notwithstanding the slight difference in 

 colour, my specimen being more nearly white than the corre- 

 sponding portion in Spengel's drawing, I have no hesitation 

 at present in identifying it as a small specimen of that species. 



A form identical with Glandiceps haekii represents the 

 Glandicipitidas. It is interesting to find this Japanese 

 species here. A few specimens (all male and incomplete) of 

 this were obtained ; the largest of them measured about 

 45 mm. in length. The animal is drawn in fig. 1. When 

 alive, the body of the animal was very contractile. I have 

 very little to add to the descriptions of the animal given by 

 Spengel and by its discoverer — Marion. 



The proboscis is conical, and has a thick base and a pointed 

 anterior end. Its dorsal surface is ai-ched, and the ventral 

 flat. Fig. 1 shows the proboscis in a fairly extended con- 

 dition. A well-marked longitudinal groove is present on the 

 dorsal side at the base, and a similar but less marked one on 

 the ventral. The length of the proboscis when moderately 

 extended is 6i mm., its basal breadth about 4 mm., and its 

 basal thickness (dorso-ventral) a little over 3 mm. The collar 

 is short, broad, and slightly depressed, its length, breadth, 

 and thickness being 2^ mm., 4.^ mm., and 4 mm. respectively. 

 The anterior end of the collar is broader than the posterior. 

 A little in front of the posterior end there is a ring furrow. 

 The trunk immediately behind the collar is narrower than 

 the collar, and compressed. Its breadth is, in this region, 

 about S^ mm., and its thickness about 4 to 4.^ mm. It 

 gradually becomes flatter and broader posteriorly, the 

 posterior end of the largest fragment being 5.^ mm. broad.
