268 ANIMAL HORMONES 



*EDH: Eupagurus-ds-rkemng hormone, dispersing red pigment in 



erythrophores of hermit crab. Source uncertain. 

 *ELH : Eupagur us -lightening hormone, concentrating red pigment in 

 erythrophores of hermit crab. Source may be in eyestalk. 

 Endocrinokinetic : of hormones stimulating the secretion of other 



hormones from endocrine glands. 

 ES : Eyestalk of decapod and stomatopod Crustacea. 

 *FSH: Follicle-stimulating hormone from adenohypophysis of 



vertbrates. 

 GXO: eNeurosecretory cells forming ganglionic-X-organ in the optic 

 ganglion of Crustacea, 

 g : Gramme. 



G.F.R. : Glomerular filtration rate. 

 H"*" : Hydrogen ion. 

 HCl: Hydrochloric acid. 

 H2O: Water. 

 HSPO: Hanstrom's sensory pore organ, a storage-and-release organ 



in Crustacea. 

 Hypophysectomy : Removal of the hypophysis or pituitary body, 



including the neural lobe unless otherwise stated. 

 I: Iodine. 



I^^^: Radioactive isotope of iodine. 

 *ICSH: Interstitial-cell-stimulating hormone from adenohypophysis 



of vertebrates. 

 *J (or JH): Sometimes used for juvenile hormone inhibiting meta- 

 morphosis of insects ; secreted from corpus allatum. 

 K+ : Potassium ion. 

 kg: Kilogramme = 1,000 g. 

 1: Litre. 

 *LDH : L/§^/«-darkening hormone, dispersing black pigment in melano- 



phores of an isopod. Source unknown. 

 *LH: Luteinizing hormone from adenohypophysis of vertebrates. 

 *LLH: Z/7]§^/fl-lightening hormone, concentrating black pigment in 

 melanophores of an isopod ; probably released from organ equiva- 

 lent to sinus gland within head capsule, 

 l.n.c. : Lateral neurosecretory cells in insect brain. 

 *LSH: Luteal-stimulating hormone from adenohypophysis of verte- 

 brates. Appears to be identical with *prolactin. 

 *LTH: "Luteotrophin", = LSH. 



*MCH: Melanophore-concentrating hormone, concentrating black 

 pigment in fish ; secreted by adenohypophysis.
